Hi Chris, I would think that, within each group of compounds (which I assume is defined up front), you'd have a hierarchical model, with a mean effect and heterogeneity. In other words, you could do a Bayesian meta-analysis. E.J.

Simon Kucharsky email me: "The bars in QQ plots are present only for Bayesian ANOVAs, and correspond to xy% credible intervals. More info is in the Don's paper: https://www.cairn.info/journal-l-annee-psychologique-2020-1-page-73.htm#. The class…

Johnny is on vacation but I asked another team member for input... E.J.

Hi Michael, Yes we made some progress (e.g., https://www.bayesianspectacles.org/preprint-default-bayes-factors-for-testing-the-inequality-of-several-population-variances/), but this has not yet resulted in changes to JASP, unfortunately. I do think …

Hi Michael, It is always somewhat of a judgment call I don't find the change from RT to ln(RT) particularly striking I was unable to get the error bars from JASP -- they do not show up for me in the Descriptives, nor in the Distribution module. Can …

Correct. But see also https://forum.cogsci.nl/discussion/6354/student-and-wilcoxon-sr-bayesian-tests-in-jasp-one-sample-a-bug#latest !! We will have addressed this in the next version. Cheers, E.J.

Yes, just change the lavaan code! Cheers, E.J.

I've forwarded your issue to one of our programmers. For future occasions, you are better off using our GitHub page for questions like these (the issue can be assigned to one of the programmers, it is easier to request and provide information, etc) …

Yes, that's one way to go. A hard-core Bayesian might want to apply all models at once instead of following a two-step strategy, but in many cases you'd arrive at the same conclusion. In general, the qualitative interpretations ("there is an ef…

Hi akiraaoki, Currently you cannot export them in one pdf file. We are working on a graph editor but in the meantime this could be a useful hack: https://jasp-stats.org/2020/07/28/a-hack-for-editing-jasp-graphs/ E.J.

Hi Gabriel, Yes, the Bayesian ANOVA is a mixed model but we didn't accommodate the long format nor did we add all the bells and whistles at the time. About the non-normality: I guess there are the Box-Cox transformations, have you considered these? …

Hi Whirly123, My guess is that these priors are possibly too wide (usually, testing priors need to be more constrained than estimation priors). One way to judge whether or not the predictions are too spread out is to generate them from the prior (An…

Well, if you want numbers like 3.2e-10 as a full number, you get .00000000032 -- this is not readable, and will wreak havoc on any table. For the p-value we do offer a setting (in preferences) to go with a specific number of decimals, and round to p…

Sorry about the delay, I'll ask E.J.

Ah sorry about that, this is a difficult time and I have not been keeping up with the posts as well as I should have. Note that this topic is about installation, not about interpretation, and you'll get more love on our GitHub account, which is wher…

Hello Kindred, Sorry about the tardy response. The prior settings affect the prior distribution for the model parameters inside the models; they do not affect the prior model probabilities themselves. When the data strongly support H0 over all other…

Yes, this is strange. I'll forward this to our expert. E.J.
-
OK, thanks for looking into this. Strange. I'll contact our meta-analysis expert.
-
I'll attend our team to this. Maybe a pause button would be nice.

Hi Nathalia, Hmmm, I was under the impression that ANOVAs do not lend themselves to a Bayesian reanalysis just from the reported information. I'll ask Julia. Cheers, E.J.

"1) When I do Bayesian tests for correlations and get a confidence interval in JASP - is that a confidence interval for the effect size or for the correlation?" For the correlation. "2) When changing my hypothesis to be one-way (in a …

Hi Miriam, It may well be the prior settings (i.e., the width of the JZS prior). I am not sure what procedure is used in SPSS. JASP uses the BAS package by Merlise Clyde. Cheers, E.J.
-
Before I bring this to the attention of our meta-analysis expert: have you executed the metafor analysis on the exact same ES and SE that were available to JASP? So if you take the csv that was analyzed by JASP, you read it into R, and you execute t…

Thanks, I'll pass this on to our team. E.J.

I'll ask, but I think this is one of the points for improvement that we were going to pick up in September. You can increase the font size with control+, but it may not be enough, and I'm not sure about the status of the keyboard shortcuts....

Hi MabelZR2020, I'll see whether we can produce an example. Cheers, E.J.

I'll forward this to our SEM expert. Cheers, E.J.

Hi JDeBeer, A googled this a little and found: "The nested t test fits a mixed model. It is called mixed because the values stacked in subcolumns and the choice of subcolumns are assumed to be random, while the treatment (teaching method, for t…
