How do I do the Poe test for WTP values derived from mixed logit models?

does anyone know anything about the difference between labelled alternatives and unlabelled alternatives in terms of estimating and interpreting choice models? can we change the unlabelled alternatives to labelled alternatives?

Good Day!

During the execution of my discrete choice experiment, I came across two crucial questions for its evaluation (with R).

1) How do I integrate the alternative "No Choice" into my data set?

2) I use the functions gmnl() or mlogit(), where there is the possibility to specify a base alternative. Is it possible to use the "No choice" alternative as reference category or base alternative? So that I can always interpret the coefficients from this one?

I hope you can help me.

Thank you very much in advance!

Best,

Christian

I am currently conducting research using a panel data - fixed effect regression model with approximately 15,000 data observations before data cleansing. However, for one of the variables (an independent variable with continuous data type), there are quite a few data points with a value of 0 (around 6,000 observations). These zero values are not missing values.

Can I still proceed with the analysis using panel data - fixed effect?

Are there any specific steps I should take to address this issue?

Thanks.

Note: I would greatly appreciate it if there is any reference literature discussing this issue

Hi everyone,

I need to convert standard error (SE) into standard deviation (SD). The formula for that is

SE times the square root of the sample size

By 'sample size', does it mean the total sample size or sample sizes of individual groups? For example, the intervention group has 40 participants while the control group has 39 (so the total sample size is 79) So, when calculating SD for the intervention group, do I use 40 as the sample size or 79?

Thank you!

I need clear differences between the above two reviews.

6 choice profiles @3 alternatives

I came across a professor who published 59 papers, mostly in SCI Indexed papers, in 2022. I was flabbergasted. He was an academic at a private university in my own country.

Today, I came across another academic who had already published 11 papers in 2023, 147 in 2022 and 206 in 2021. I occasionally see similar researchers with over 20 papers published in a year. OK, some researchers are in a research group. They write in groups, so their names are on more papers than those who work solo. (or those academics whose institutions do not have research centres). I do not want to breach ethical issues and be discriminative. Still, researchers from India and the Middle East often find a colleague who works at a reputable European/US University and includes their names on their papers. So it is a win-win; they publish their papers, and reputable academics get citations and papers and further increase their reputation. Of course, those papers are peer-reviewed and published so I am not questioning the quality of the papers. Universities (particularly in developing countries) are pushing researchers/academics to publish more papers in an era where only published papers, citations and Hi indexes count, OK collaboration is important but as a novice researcher and PhD student, I found it very discouraging.. seeing people with 206 papers published in a year..

Last week on ResearchGate 3 new cites where identified on one of my papers. 1 from December 2022 and 2 from January 2022. How long does it take for Google Scholar to sync with ResearchGate and identify the new cites?

Also, I have noticed that generally there are more cites on Google Scholar on certain papers and more cites on ResearchGate on others? Does anyone know the reasons why?

I would imagine Google Scholar is picking cites from multiple sources which would explain why there are more cites on some papers on Google Scholar. The papers with additional cites on ReseachGate maybe just haven't sync'd with Google Scholar yet, I am assuming?

I'm doing my master thesis at the moment. For my analysis, I have to use process macro. I'm doing a mediation (model 4) with some control variables. I understand the results from this analysis but not how to put it in a table. This is how my promotor wants te to do it. Can someone explain me which information you use? Is it only the information from the 'a' path? Or is it from another path? Thank you!
