I suspect this is an old issue related to whether or not to pool an error term, but I've asked a team member just to be sure. Regardless, thanks for bringing this up.

Hi Mila, Good timing, we have started a project to get to the bottom of this. The discrepancy seems to center exclusively on repeated measures ANOVA. Do you have an example data set you could share? Cheers, E.J.

Hi Francesco, I would guess that if you use something like EBICglasso, the cutoffs are based on EBIC, not on a p-value. But I'll ask our experts for clarification. Cheers, E.J.

Hi Liesbeth, PLS SEM is not yet possible in JASP, but we have it on our radar. Otherwise, JASP uses Lavaan syntax, so whatever works in Lavaan will work in JASP (which is really just a GUI on steroids for R and R packages). Cheers, EJ.

Hi Elise, This is presently not possible within the new mixed model functionality. However, the Bayesian ANOVA in JASP is based on the BayesFactor package in R, and this implements a mixed model. So it should be possible, but honestly I haven't chec…

I've asked our SEM expert for advice (sorry about the tardy responses, I've been absorbed by the demands of online teaching, only catching up now...) E.J.

Hi Michael, Thanks for your post. My answers, briefly: The reason not to use a parameter estimation approach for hypothesis testing is because these are different endeavors that address different questions. See for instance Wagenmakers, E.-J., Lee, …

Have you confirmed that your variables are not nominal? Maybe you could send along a small part of your data set (or some made up values) as a .jasp file so we can give it a go? E.J.

Hi Cathy, This would be good to have. I'll make some inquiries. Cheers, E.J.

Hi Rohanp16, Not sure about the workings of brms. We once coded this in WinBUGS (http://www.ejwagenmakers.com/2009/WetzelsEtAl2009Ttest.pdf). The Lee & Wagenmakers (2013) textbook (https://bayesmodels.com/) also provides JAGS/Stan code. Ioannis …

Hi Liesbeth That is really strange. We are aware of some bugs that needlessly created large files, but not being able to open files you have created is a serious issue that we wish to resolve. But I am not the right person for this job -- this needs…
-
Update: no, there is no way to do this currently. There is a recurrent discussion within the team, but without having reached consensus on whether and how to implement this. Cheers, E.J.

Hi sjp, This is more of a question for the programming team I think (I'll attend them to your post), so a discussion for our GitHub page I think Cheers, E.J.

Hi Stephanie, This question is best posed on the JASP GitHub page, where our programming team can help you out! For details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/ Cheers, E.J.

This is strange. There is always the option to unzip the JASP file and view the .html output file, but for a better solution please post this issue on our GitHub page so our programming team can assist you efficiently. Cheers, E.J.

Maybe it is a good idea to go over some of the examples in papers such as this one here: van den Bergh, D., van Doorn, J., Marsman, M., Draws, T., van Kesteren, E.-J., Derks, K., Dablander, F., Gronau, Q. F., Kucharsky, S., Komarlu Narendra Gupta, A…

Dear Raquel, Just to get this straight (because it is a little unusual): you have one continuous variable (say income) and you use this to predict two categorical variables (say gender scored as male, female; and haircolor, scored as black, brown, b…

Hi Anton, What test are we looking at? If you seek a p-value for something non-normal, there are options: Use the nonparametric bootstrap Use rank-based methods Apply transformations. Cheers, E.J.
-
No neural networks yet in the ML module, I think. If you have suggestions on what R packages to include, and what functionality to support, that would be welcome! You can make feature suggestions on our GitHub page. Here is the list of ML methods we…

:-) thanks, I was about to ask our experts E.J.

No worries, good to hear

Hi Nickytran1, That's unfortunate, and we'll try and work out what is amiss. For technical issues such as this, please contact the programming team on our GitHub page -- you will get instructions on what to report exactly, and the right team member …
-
Hmm that is not good. For technical issues such as this, please contact the programming team on our GitHub page -- you will get instructions on what to report exactly, and the right team member can be assigned to your issue. For details see https://…

Hi Narcilili, "I wonder if Bayesian linear regression cannot be used if the predictors are categorical." Yes, this is correct. Currently the prior structure is set up so that the results are invariant under changes of the measurement scale…
-
Hi Liesbeth I'll forward this to our team. If you want fast help on such issues in the future, your best bet is to post the issue on our GitHub page, because then you can contact the programmers directly, and you'll get guidance on what you need to …
-
You could call the groups 1, 2, and 3 and pretend you're OK (this will violate assumptions, but when you are wiling to add VA and VB as predictors this should not worry you perhaps)
-
Quick response: my first thought it to include both weight and group as predictors, and then add the interaction (which is of interest) Cheers, E.J.
-
Hi Liesbeth This has been revamped. We hope to present a much improved version shortly. Cheers, E.J.
-
It's difficult for me without the substantive background knowledge, but I am not sure this is an issue. You basically have 500+ effect sizes delta_i, and we assume that delta_i ~ N(mu,sigma). I guess in the usual setup each test is for an experiment…

This issue is continued on GitHub. E.J.
