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…

Thanks for the suggestion. This is definitely an idea that is on our agenda, but we have some bigger fish to fry first... Cheers, E.J.

[Solution at the end] Strange. I can get the second number. So, in R: prior.odds <- .4/.6 posterior.odds <- .1524/(1-.1524) posterior.odds/prior.odds [1] 0.2697027 [The table gives 0.28, but that is probably just rounding] I'm not really getti…

Dear JLeborgne, Thanks for the suggestion (NB. on the JASP GitHub page, you can choose between "bug report" and "feature request" -- but I'll pass this on). To respond: We will add more plotting options to RM ANOVA, similar to wh…

Hi mdt, Point taken, but logistic regression is actually relatively well documented. Granted, details on the robust standard errors appear to be missing. I'll ask the team member who implemented this! Cheers, E.J.

Dear Zambia, You have seen have you seen this: https://jasp-stats.org/2020/03/12/mediation-and-moderation-analysis-in-jasp/ Cheers, E.J.
-
Well, I think you could consult the work by de Vries and Morey: https://www.sciencedirect.com/science/article/abs/pii/S0005789414001300 It should have references to classical tests as well I think Cheers, E.J.

I suggest contacting Herbert Hoijtink, since BAIN is his baby :-) Let us know what he says! E.J.

Hi August, Yes. In the upcoming version you can save the graphs as pptx, which allows you to edit them. E.J.
-
We will be testing the new version this week! Cheers, E.J.

Hi Garycarmel, If you take a look at https://jasp-stats.org/2020/06/09/finished-the-jasp-data-library-1st-ed/ the last chapter is on missing data. In the future we hope to do something more fancy. E.J.

We have this under development. So it will be possible soon, but not right now! Cheers, E.J.
