Questions related to Process Analysis

My lab wants to try to do as much of our pre-processing, processing, and analysis in R as possible, for ease of workflow and replicability. We use a lot of psychophysiological measures and have historically used MATLAB for our workflow with this type of data. We want to know if anyone has been successful in using R for these types of tasks.

Any good R packages?

I'm working on my thesis recently, and got some technical issues on running SPSS.

My research model is based on process 25, but in process theres's no model 25 to run.

Therefore, I ran model 21 instead. I put 3 way interaction and 2 way interaction in covariates,

but I found there's mistake on estimating index of moderated moderated mediation.

Could anyone help me with this situation? It'll be great if you have template or syntax.

I've already checked on the Hayes' bibliography of mediation, moderation amd conditional process analysis, yet still no clue how to fix the trouble.

Follow up: I chose model 7 instead, and put 2nd-stage moderator and its interaction with mediation in covariate.

But still with question, the 2nd-stage moderator and its interaction would predict twice, first time is when the outcome variables is mediation. Is it okay?

I've been hearing from several people lately that using the Hayes PROCESS macro is ill-advised, but I've yet to see any formal explanations or empirical data to support this. Can anyone suggest articles that either (a) address these limitations or (b) address why the use of the program isn't a problem? I've been running into paywalls with the few articles I could find.

Either way, I would like to understand the rationale. I love the PROCESS macro and would like to know if there are legitimate criticisms.

Below are some issues related to Big Data database technologies that can be developed scientifically:

- Application of data processing technology in Big Data database systems for modern education 4.0,

- Improvement of forecasting of natural, climatic, economic, economic, financial, social etc. phenomena based on analyzing large data sets,

- Analysis of sentiment, opinions of citizens, Internet users regarding brand recognition of companies, customer reviews of specific services and products, views on various topics, citizens' worldview based on the analysis of large collections of information downloaded from various websites, from comments downloaded from social media portals,

- Analysis of information and marketing services of commercially operating companies that carry out specific analyzes of sentiment, citizens' opinions, Internet users regarding brand recognition, customer reviews of specific services and products etc. on behalf of other companies that purchase specific analytical reports,

- Analysis of the possibilities of cooperation, synergy, correlation, conducting interdisciplinary research, connecting Big Data database systems with other information technologies typical for the development of the current fourth technological revolution called Industry 4.0, which include technologies such as: cloud computing, machine learning, Internet of Things, Artificial Intelligence, etc.

I have a quite complex model to run in SPSS Process with

- 4 groups in the categorical IV

- one mediator

- metric DV and

- three potential moderators.

Three moderators is not provided in the SPSS Process input field, therefore in order to reduce the complexity of the model

**before running the Process analysis, I want to test if the moderators are significant at all**.If not, I want to delete the insignificant moderators so I can estimate a reduced model in Process.

- Is there a way to check for significance of moderators beforehand in such a complex? (each moderator is hypothesized to influence two effects (direct effect of IV on DV and indirect effect of IV on DV)

Or is the model too complex to check beforehand and I just have to run the complete model multiple times in SPSS Process?

Any feedback is much appreciated! Thank you so much

I have a conditional moderated mediation (Hayes Model 58) that I found is only partially significant through the Johnson Newman technique. We need to convert the variable into a dichotomous variable to find the index of moderated mediation.

Traditional approaches such as a mean split or median split may not be ideal because the conditional effect I found only applies to scores up to a certain point.

Could I group the values that do have a significant effect together vs the rest? Has anyone seen examples of this being done in a marketing journal?

Hi,

I am conducting a cross-sectional quantitative study, originally i was using 4 predictor variables and criterion and used multi-regressional analysis. This was significant and lead to three of my four predictors being supported.

pearsons correlation indicated these predictors were correlated the variance inflation factor (

*VIF*) and tolerance indicated this was no an issue (low-moderate VIF and high tolerance) as the correlated variables were significant predictors.predictors: professional self-doubt, developmental depletion and developmental growth (whether participants think they are growing in their careers). i also had years of experience that was non-significant. he criterion is well-being

I ran a serial mediation analysis using model 6. using a theoretical basis i added predictor variable 'self-doubt' as a predictor. developmental growth, developmental depletion and years of experience as mediators . well-being as the criterion.

the pathways between each variable and the criterion are the same as those found in multi-regression. indirect pathways were also found for developmental growth and depletion. depletion also influenced the link between growth and well-being. Is it reasonable to conclude these variables have direct and indirect effects on well-being?

The aim of my study is to see how these factors impact well-being.

Moderated mediation (or Conditional Process Analysis, called by Hayes https://journals.sagepub.com/doi/abs/10.1177/0002764219859633?journalCode=absb)

It can be applied by Lavaan package in R (https://stats.stackexchange.com/questions/163436/r-moderated-mediation-using-the-lavaan-package).

However, it rarely seen be used in biological study. I want to know your opinion on this method. Is it be widely recognized by editors? Has it been used by papers in journal(IF>10)?

Thank for your attention！

I am in a process of analysis of my research data and want to make logical membe function. Please guide.

I am using data of 25-year interval, one dependent variable and 5 independent variables, all are time series in nature. I would be grateful for a step by step help in the process of analysis with STATA using the ARIMA model, do I differentiate all the independent variables to test for stationarity or I only do that to the dependent variable? Thank you.

Currently, the only source of an LSA standard is from THC Pharm in Germany. I tried to apply for this standard, but the paperwork was insufficient and provided several obstacles to obtain the standard. I am currently wondering if there are any U.S. based company that has the LSA standard? If not, I have read a few papers which use a similar compound to LSA in order to proceed with their analyses. Since I am using LC-MS, it would be ideal to have an LSA standard - but I am open to researching other options for this Master's Project.

Are there python (Machine Learning)script codes libraries for satellite images pre procssing and processing analysis or feature extractions.

I want to quantify the change in fluorescence (brightness) to a reference picture. Please, suggest and guide for the procedure and possible software/programming or program? If literature is linked it will be great help?

Here is a summary of my research design:

X: Continuous behavioral variable (i.e. frequency of viewing specific television content)

M: Continuous attitudinal variable

Y: Continuous attitudinal variable

Controlling for some other variables, I ran an SPSS PROCESS simple mediation model (Model 4), and I found significance for the direct path and one of the indirect paths. I wonder though - do I have to satisfy certain assumptions to be able to, in the same paper, report results from both the said PROCESS analysis as well as those from hierarchical regression where all the variables that I had entered into the PROCESS analysis? I have seen some papers that did this, but wanted to get more wisdom on this matter.

I need to have information about the complex modulus (G*) of a certain PVC plastisol recipe I'm currently developing and the only equipment I have available is an RPA 2000. What I really need to know is how should I know which is the best frequency to do a temperature sweep in my material? I already made some tests but I couldn't really find any information about the correct test standard to use and the most appropriate frequency to do the measurements. Can someone please help on this?

Thank you very much.

Is this possible? The negative moderation effect is small (both effects are significant). The mediation simultaneously included 6 other variables, another 2 of which also mediated the relationship between SK and SU. I just want to know whether this is statistically possible, but I also need some help to interpret what it means. Thank you.

Is there a seprate library for process variation (process corners) or monte carlo analysis of the circuits based on carbon nanotube field effect transistors like MOSFETs?

Could we use process corner analysis for all variations of CNFET(e.g. the number of cnts)?

Hello all,

I have carried out Solid Glass particle impact on AL 6061-T6 plate. I have verified my results with Experimental values and they seem to match well for different velocities and different particle sizes. However i came across a paper stating that the SPH model is said to be appropriate if the Total Energy remains constant over the entire process.

I find that my Total Energy fluctuates very little, so is it acceptable ? also the internal energy and kinetic energy seem to have little fluctuations in them after impact. I'm attaching the files explaining the Simulation Model and the Energy charts, please let me know if they are acceptable or are they supposed to be constant with time after impact.

I ran initially a causal steps approach between a variable (A), a predictor (I), and a moderator (G).

Using this approach i found that A correlates to I; I correlates to G; A correlates to G

and entering everything into the model shows a full mediation of I through G for A (i.e. I is no longer sig for A).

Then I decided to use PROCESS and it did not find the initial I and G effect to be significant, and the indirect effect was not significant. finding a single effect of G on A.

I know it's confusing, but which one should I trust? maybe I did something wrong in PROCESS?

Help!

I test the moderating effect of categorical moderator (consumer ethnocentrism (CET)) to the relationship of perceived quality and purchase intention. The result of model 1 of PROCESS macro (moderation) shows that the interaction is not significant (p>0.05). However, the Conditional effect of X on Y at values of the moderator(s): table shows the significant of both group (high and low CET) In this case, is it mean that CET does not moderate the relation between perceived quality and purchase intention?

Thank you very much for your help.

How can I identify products solubilized in high boiling solvents such as ethylene glycol, DMF and DMSO using GCMS?

In detecting Multivariate outliers, many researchers recommend using Mahalanobis Distance (MD) technique. In SPSS, such function is readily available by assigning the Dependent Variable, and Independent Variables via regression analysis tool (Regression > Linear > Save > tick Mahalanobis). An output of MD scores will appear (MAH_1). Another new variable that reveals the upper-tail probabilities of MD is created by computing 1-CDF.CHISQ(mah_1, X). X refers to the number of predictors. Any cases with values below 0.001 indicate multivariate outliers.

In my case, I am testing 3 continuous Independent Variables, and 5 continuous Moderator Variables. The specific moderation tool used is the Conditional Process Analysis SPSS-Macro Model 1 (Hayes, 2013). My question is, what is the number of predictors (X) that I should use in running the MD test as described above to discover Multivariate outliers? Other than IVs, should I take into account moderators in the number of predictors?

IMHO, moderators are considered as predictors that change the effect of IV on DV. But at the same time, there is a clear distinction between the effects of IV and MV (interaction), and as such MV is not a main predictor of interest (in predicting DV).

I am going to find the magnitude of 3 way interaction. I read A.F Hayes's book "Introduction to mediation, moderation and conditional process analysis", wherein I found the results of his sample data which is also run by me through hierarchical regression method. The question is that A.F Hayes uses the unstandardized beta of step 3 of hierarchical regression while in many articles all steps of that are used. Would you help me in clarifying the mystery. The reference file containing data is attached.

Thanks.

The answers for each question is likert scale (1=strong disagree, 2=disagree, 3=Neutural, 4=agree, 5=strong agree). I have collect the 101 effective responses.

According to past literature study, some researchers used PLS method for the analysis. But I have little knowdge on statistical analysis. could you kindly please how to process this analysis from likert scale data to the data for PLS?

By the way, one stupid quesiton, what is the" loading" how to calcualte the "loading" for each questions?

Really appreciate your kind advice!

Dear all,

This is more of a survey than a question. I stumbled across the Julia language (julialang.org), developed at the MIT as a faster, more flexible and open source alternative for languages such as MATLAB, Python, R and others, when Dougles Bates announced that he would prefer Julia over R for further development of his linear-mixed effect modeling package.

How do you estimate the probability that Julia will replace well-established languages such as MATLAB, R or Python soon? Are you planning already on moving to Julia for teaching statistics instead of using R? Is there someone among you working already on Julia packages for the processing and analysis of EEG-, fMRI- or eye-movement-data?

There are different causes for foaming in Amine absorber for gas sweetening in natural gas plants including: 1)heavy hydrocarbon accumulation, 2) solid particle , 3) antifoam problem. Do you think that the foaming due to these causes are different?

I want to monitor the absorber by the various measurements (flow, temperature, pressure). Do root causes can be diagnosis based on measurements?

I know about Bland Altman techniques and the approach of looking at inter subject repeatability. I have 2GB of data and per subject I have at least 10 repeated observations.

How big should my sample be to give me a better understanding of the whole population, and in case of big data, are the techniques like Bland Altman still valid?

I am interested in the analysis of process reliability in the workplace to uncover the production gaps and/or the unreliable processes that might exist in my organisation. I know that WinSmith Weibull software permits such an analysis, but are there any more effective tools/software other than Weibull that one can use? Also, how critical is it for operations management to conduct these types of process reliability checks to conduct the day to day quality control?
