I was producing vegetation indices in a study area in the tropics with MOD09 product (Land Surface Reflectance, 8-days, 500m) and also with MOD13 (Vegetation index, 16-days, 500m). I got more or less the same result with some small differences due to the fact that the former product is an 8-days composite and the latter is 16-days composite. But I noticed that the quality flag are completely different, the one from MOD09 is very 'permissive', the could masking is almost unnecessary but with MOD13 is the opposite, because I lose a lot of data due to clouds. I think that the QA flag of MOD13 should be the correct one because my study area is in the tropics with high presences of clouds, but I wonder why the QA flag of MOD09 is so different and seems to be unreliable.
Can someone give me a clue?

Thanks for your reply Prof. Hack. And yes, I have used the quality flag as it says in the guidelines. I will take a look to the paper you just recommended me.

I have had half-hourly downwelling shortwave infrared data for almost two years. It contains large missing values and cannot be used for modeling purposes. As shortwave radiation data include seasonality and varies each day, I tried na_seadec() in R to resolve the issue. But I am obtaining negative values in missing data, though the data do not contain any negative values, and for huge gaps, a kind of increasing pattern is interpolated. I tried the Arima model, but the problem persists, especially for huge gaps.
Please find the articles I went through to attempt this issue.
1. (PDF) Challenging Problems of Quality Assurance and Quality Control (QA/QC) of Meteorological Time Series Data (researchgate.net)
2. Chapter 48 Time Series Modeling with ARIMA in R | Community contributions for EDAV Fall 2019 (jtr13.github.io)
The data is from 09/03/2017 to 31/12/2019. While working with the Arima model, Kalman smoothing the error faced was that seasonality is less than two years.
Kindly help.
I am attempting the problem in R software. However, any help in python would also do.
I appreciate any help regarding this issue.
Thank you
Relevant answer
Answer
Hi Richa. Plain-vanilla ARIMA models will not help you because (in principle) they are not designed to manage those gaps. You need to get deeper into a model/estimation method that allows you to specify all those missing data points as non-observable variables to be estimated together with other non-observable variables in the model. I am sure the following (old) reference will help you:
A. C. Harvey and R. G. Pierse (1984) Estimating Missing Observations in Economic Time Series, Journal of the American Statistical Association, Vol. 79, No. 385 (Mar., 1984), pp. 125-131.

I am currently studying QA systems in NLP. I found that the term MRC and QA System are interchangeable. Then, I found this page https://www.quora.com/What-is-the-difference-between-machine-comprehension-and-question-answering-in-NLP that states MRC is an approach to solve QA problem. what is another approach?
Relevant answer
Answer
QA systems can be roughly divided into:
  1. Query processing
  2. Database storage(e.g. GraphDBs, unstructured documents,SQL, etc. which goes to the processing for storage and retrieval on such information) architecture and methods of retrieval
  3. Document processing(e.g. extracting the relevant piece of information after it has been extracted from the storage)
  4. Answer formatting (e.g. frame filling, etc.)
Each stage can include multiple approaches. Could you be more specific on which part of the QA system are you interested on?

Hi there,
how are the values in ST_QA (layer about the uncertainty surface temperature given in the ST band file) supposed to be interpreted? Is it an absolute value and therefore interpreted similar to standard deviation?

According to my experience Automation test team can come to play their role once after the Manual test team tested several cycles and the product or function comes to a certain, level of stability.
Relevant answer
Answer
Test automation developers and manual testers should have totally different skills. An automation team's focus will be different from that of a manual team's. Good manual testers provide a lot of skills that cannot be automated such as exploratory testing, understanding the context of the SUT, company, and industry, knowing the right questions to ask, and the ability to empathize with different groups of stakeholders.
That isn't to say that test engineers can't develop those characteristics as well, but it's not (or at least shouldn't be) the focus of their job.

Hello,
I am completing a research project using a computed tomography simulator and a phantom with 16 inserts of various known densities. Regions of interest are placed on these 16 inserts. A mean value and standard deviation are recorded for each insert. A software is used to manipulate the images and and the same ROIs are used to record the mean and standard deviation. So for any given insert we have original (mean and standard deviation) and post-processed (mean and standard deviation).
I am repeating the computed tomography scans using the same parameters over a period of time and processing the images using the same software to assess consistency of manipulation by the software. So i would like to compare the difference between (original and post-processed dataset #1) and (original and post-processed dataset #2)
I am unsure how to approach this and what statistical test to use in this case. Any suggestions of where to start?

Answer
Dear Bhoj P. Singh,
No government in India has successfully formulated policies to manage the country's human population growth, which stands at 1.6% a year, down from a high of about 2.3% in the early 1970s. India is forecast to become the world's most populous country in 2030, up from 1.35 billion today to nearly 1.55 billion. The two main common causes leading to over population in India are: The birth rate is still higher than the death rate. The fertility rate due to the population policies and other measures has been falling but even then it is much higher compared to other countries. The formation of a national Indian planning commission for population control is viewed as necessary for motivating all people to reduce population size. More statistics are needed in India on environmental measures and population. Environmental degradation lowers economic status, which in turn contributes to poverty. According to a report in the Times of India (6 May 2010) the government of India will not introduce legislation to reduce population growth. Report said, “Population is a major concern. India is the world's second most populous country. Urgent steps need to be taken to stabilise the population for sustainable development.”
Below are the most effective measures which can be employed to control population growth:
1. Development.
2. Easy and Cheap availability of Contraceptives. ...
3. Education. ...
4. Eradicate Poverty. ...
5. Women Empowerment. ...

Big Data database systems can be very diverse, because they can be different in virtually every respect. In individual institutions and companies in which Big Data database systems are built and developed, they may differ, among others: 1. Technical and technological characteristics of servers, disks and other elements of IT and network equipment, potential of data processing speed. 2. The type and generation of operational database systems supporting specific Big Data databases. 3. Installed applications for archiving, indexing, searching and analyzing information collected in database systems. 4. The possibilities of expanding and improving specific, existing Big Data database systems. Therefore, if there is a need to accurately compare specific Big Data database systems functioning in institutions and companies, then a universal, multi-faceted, multi-factor scoring model should be built, thanks to which it will be possible to conduct such comparative analyzes.

Answer
Hello Ankita,
opinions are divided. There are analysts who advocate this and there are also analysts who regard it as manipulation of results. If I were you, I would report the result including recovery. With a recovery close to 100% (above or below) the error is not very large compared to the uncorrected result. In addition, recovery is an important quality criterion, as you have performed your analytics. With values around 100%, you seem to have done everything right. If, for example, a recovery value of 60 % would come out, then I would think about the entire workflow.

Relevant answer
Answer
Suvadip,
From the context of your affiliation with the Atomic Energy Regulatory Board and from Paul Butchart's reply, I assume that you are focused on nuclear energy. Paul's answer is very good for the focus on nuclear energy.
If you need more general information, standards, or tutorials, then the International Society of Automation (ISA) may be useful. In particular, this ISA webpage may give you some direction: https://www.isa.org/standards-and-publications/isa-standards/.
I am guessing from the brief overview description of your project that you might be involved with developing assessments and qualifications for COTS instrumentation and control systems. If you need general approaches to hazard analysis for system safety, I recommend two books:
1. "Hazard Analysis Techniques for System Safety," by Clifton A. Ericson, Wiley-Interscience, 2005.
2. ""Engineering a Safer World: Systems Thinking Applied to Safety," by Nancy G. Leveson, MIT Press, 2011.
There is also the International System Safety Society, with a website at: http://www.system-safety.org/ , that may be of use to you.
Finally, my own textbook, "Mission-Critical and Safety-Critical Systems Handbook, Design and Development for Embedded Applications," Edited by Kim Fowler, Elsevier, 2010, may be of some use. It has specific examples found in medical devices, spacecraft, and military equipment. It does not have anything specific to the nuclear energy field.
Your question is very broad, but it does need to be asked. Many people have tackled aspects of testing certification and qualification over decades. I am not sure there is a definitive approach, other than what Paul Butchart has already given you.

I am working on an HPLC method that separates our target protein from other excipients in the formulation. The goal of this method is to determine the concentration of protein in our sample. We do this by utilizing a standard of known protein concentration to determine the concentration of our unknown.
The standards are prepared (on the bench) at varying concentrations. 50 uL of each standard and sample are injected. The standard peak areas are used to create a linear standard curve against which the concentration of our sample is derived.
This method seems pretty straightforward and not uncommon. However, I am wondering why we cannot take our standard and inject different volumes (e.g. 10 uL, 30 uL, 50 uL, 70 uL, and 90 uL) and create a standard curve from this. It would save a good amount of time in running the assay.
I approached QC and QA about this, but their response was that no one does it this way because this type of method can't be validated. You can't be confident that all different instruments will inject the correct volume of standard for you. Any thoughts?
Relevant answer
Answer
It is the mass on column that is relevant and not the injection volume. In addition, you need a 'pure' 99% standard. The method MUST comply with ICH Q2(r1).

I have been selected for the Quality Commission of my university, and we will start preparing internal evaluation report soon. However, a revision will be necessary about the strategic plan of the university and the KPIs for monitoring internal quality (education, research and administrative quality). I recently read a paper and there was an interesting example about determining stragey based on KPIs rather than vice a versa. This actually made sense since main KPIs are already fixed/widely used on national/international levels (like qualification frameworks, and policies of central higher education commissions), and many HEIs do not have the autonomy or the power to change these expectations. So here is the question: Is it better to determine strategy based on pre-established KPIs when compared to determining KPIs based on strategy?
Relevant answer
Answer
Dear H. Serkan Akilli,
Many university nowadays make the same move -- have the pre-established set of KPI (for example, the desired rank in the Times, Shanghai Index etc.) and them put any efforts to reach the formal indicators which correspond to the rank "Xth minus Y". The results are usually awful -- see the enclosed the classical paper on the consequences of stretch goals.

Sequential-Sampling Plan can be defined as a further refinement of the double-sampling plan, in which we randomly select items from the lot and inspects them one by one. Each time an item is inspected, a decision is made to accept or to reject the lot. But is there a particular limitation for the number of samples that we can draw out in this method?
Relevant answer
Answer
Yes, the curtailment sample size is just that; the maximum cumulative number of samples for a given sampling plan. If no decision is made and the curtailment sample size has reached the limit, no further sampling is required. Make a decision on the lot disposition, accept or not. This situation can happen (in theory) but with either good or poor quality the decision is made with the smallest average sample number compared to all other attributes sampling. See ISO 2859-5

Answer
I would not accept that an order for medication to be administered by oral route can automatically be administered by nasogastric or PEG tube. Prior to administering (and indeed ordering) any medication via the enteral route the practitioner needs to take into account the formulation, potential interaction with feed, type of tube, site of placement, and site of drug absorption for each medication. The practitioner ordering the medication should seek the pharmacists advice or whether the medication can be administered enterally (which in most cases involves crushing or dispersion eg., Omeprazole and others eg., enteric coated - thus slow release medications cannot be crushed. Each hospital usually has a list of medications which can be administed enterally

I have an extremely high R^2 (Pred) of 96% and R^2 (adj) of 99%. Using Minitab's response optimizer I generate a confidence interval and prediction interval for specific settings. Yet when I get to the shop floor to test these settings my results are generally out of the interval. 
The intervals for specific settings are generally .002 wide which is extremely tight for machining processes. 
I am assuming the operator is having a significant effect on the parts.
Have I over fitted the model? Taking out terms reduces the R^2 (pred) but it widens the intervals which may be more relevant.

Typically, a Quality Assurance (QA) program has at least 2 goals, which are:
  1. Establish that the software meets the stated requirements.
  2. Minimize the number of errors in the deployed software.
Measuring the QA processes effectiveness to these goals is straightforward (coverage and count reported errors), but the second goal may take years to identify the escaping errors. This brings us back to the question. To make a QA process more effective (meeting goals and costs), we need to know the characteristics of a QA process. Understanding the characteristics of a QA process also provides a basis to evaluate new techniques that may improve both the effectiveness and reduce the cost of quality.
Relevant answer
Answer
Carl,
The viewpoint of a stakeholder as to requirements completeness is entirely different than that of QA. For a business application, the requirements are generally very inadequate for the purpose of QA. In this case, QA needs to play an effective role in making the requirements more complete as to enable better testing. So, one characteristic is to either include QA as a stakeholder or include a requirements review and possible cleanup phase as part of the process.

What we need is a pointer for picking spatial points inside buildings and their rooms, and 3D software which can convert those spatial data
points into a 3D model.
We want to pick floor and ceiling points for corners, and frames of windows and doors and hallways and wall-shape-transitions, etc. The idea is
to save a ton of time taking and scribing measurements with conventional tools, and getting actual accurate shapes of rooms into the model very
quickly.
The model would be imported into Revit for further work, and remodeling to prep for visualization and walk-throughs.
1. How can we get this done, and with what hardware and software?
2. Perhaps finger tracking could work for this, and we would need to know who to contact for more information and possibly assistance
implementing.
3. This seems like a great R&D project if a system is not currently available. We can make resources available for QA testing at NMSU.
We had considered that Kinect might be used, but expect it would not provide accuracy or be useful with a set of procedures that work the same
in all rooms. We expect that something like an ultrasonic system with wand and reference unit would be useful and accurate for these purposes.

From a strategic HRM perspective, you could also look at the literature on High Performance Work Systems (HPWS). These are sets of HRM practices that should be beneficial both the the organization and for individual employees. An often cited overview of the literature was published in 1998 by Becker et al. (Research in Personnel and Human Resource Management). More recent papers include Evans and Davis (2005 in Journal of Management 31, 5), Boxall and Macky (2009 in Human Resource Management Journal, 19, 1) and Van de Voorde and Beijer (2015 in Human Resource Management Journal, 25, 1).

1. Cost of quality (COQ), quality related cost, 
2. Lifecycle cost (LCC)
3. Total ownership cost (TOC)
Relevant answer
Answer
Dear Zhou,
Cost of quality is the economic value of all activities/resources needed to achieve quality.  Many authors recognize four types of quality costs:
1. prevention costs, such as personnel training, product/service design, supplier selection.
2.. appraisal costs are those related to quality assurance and quality control activities carried out during or at the end the production process (process/product inspections or lab tests)
3. internal failure costs: the economic value of activities related to the occurrence of failure in products or service (reprocessing, product repairing, waste, extra man hours, etc.)
4. external failure costs: related to activities an organization has to undertake when the client detects a failure in our product or service (warranties, legal actions, replacement, extra freights, etc.)
You cannot expect to reach zero COQ, but the manager's task is to minimize total COQ, by an optimal combination of the four types of costs.
Many authors also recognize intangible costs, like sales lost to actual and future clients.
Unfortunately, I'm not an expert in LCC or TOC, but I hope you'll find my answer a littel helpful.
Kind regards,

What is the difference between residual solvent and moisture content?
Relevant answer
Answer
By definition, moisture content is the ratio of the mass of water in a sample to the mass of solids in the sample, expressed as a percentage.
For pharmacopeial purposes, residual solvents in pharmaceuticals are defined as organic volatile chemicals that are used or produced in the manufacture of drug substances or excipients, or in the preparation of drug products. The residual solvents are not completely removed by practical manufacturing techniques. Appropriate selection of the solvent for the synthesis of a drug substance or an excipient may enhance the yield, or determine characteristics such as crystal form, purity, and solubility. Therefore, the solvent may sometimes be a critical element in the synthetic process. However, the content of solvents in such products should be evaluated and justified. Because residual solvents do not provide therapeutic benefit, they should be removed, to the extent possible, to meet ingredient and product specifications, good manufacturing practices, or other quality-based requirements. Drug products should contain no higher levels of residual solvents than can be supported by safety data.

I am doing my research in enhancing agile methodology by improving overall quality. Number of challenges are there in agile. Which quality model used in companies for agile quality assurance?
Is there any data set of agile project available?
Relevant answer
Answer
There are over 50 quality attributes (e.g. safety, security, portability, etc.).  These attributes are NOT specific to Agile nor any development strategy. They are specific to the requirements of the system being built or modified.
Different strategies are more or less effective in specifying, achieving, and verifying different quality requirements.  While Agile can be very effective in deal with functionality, most Agile methodologies fail to address quality attributes effectively.  XP effectively addresses 4 of them. 
An Agile team may address quality effectively, but only by ignoring most of the advice that Agile provides.  For example, quality attribute requirements should be identified early and often.  This is contrary to the Agile antipattern of Big Requirements Up Front.

This question born because I have a disagree with a partner: we need to measure a property in a material, but the method is not standardized, and when we request to a third party lab they have not accredited technician for do it even they have not certification for the test, so that he said that there is no way to probe that the methode he uses is wrong, because the lab cannot reproduce it in and accredited way. Obviously for me is totally wrong, because even when you have not accreditation, if you have the conditions to reproduce the experiment with the same or better exactitude and presicion degree you can do it no matters you have an accreditation or a third part validation. I think about the scholar and prived research that make experiments under certain conditions of control, but need not any accreditation (of course can be wrong but not to be imposible to be verify).
Relevant answer
Answer
I would like to agree with the views of our colleague Chris Harrington but add some more points. In case the method is not a standard one, a full validation needs to be carried out in the lab. To this end, the Eurachem Guide on validation could be very helpful. Further to this, in case the laboratory could not find any commercially available PT scheme for the particular parameter and matrix to participate in, a more detailed IQC could be used. In case no (certified) reference materials are available for use in the IQC, routine lab samples could be used under conditions maintaining there stability for a certain period. Furthermore duplicate tests could be carried out by more than one        competent and authorized (not "accredited") members of the staff.

Not necessarily as these Agencies do not always take into consideration the culture of the immediate society/institution. I know from experience in the Caribbean, some internationally funded projects at some institutions failed to meet accreditation standards and were not accredited by the International Agencies. In one instance that involved setting up a garment construction training institution with a workforce component, whereby trainees can work and study, the international accreditation standards required that the trainees/employees be searched everyday on leaving/entering the compound. Well, students were not use to such measures and did not subject themselves to these searches. The latter affected the success of the project negatively.

However, the major challenges in this sector are with the overall quality, safety and efficacy of these products. The claims and other information provided on the label may be far from what is in the pack. Just because an herb is natural does not mean that it is safe. Nevertheless, if herbal products are to assume a respected place in the market and society, more reliable and credible means and ways as well as greater authoritative regulatory directives for quality and safety of the herbal products are warranted.
