Yes, but I believe that substantive hypotheses usually translate to ordinal expectations. We have developed something like this for the multinomial, see https://psyarxiv.com/bux7p/ Cheers, E.J.

Hi Danilinares, Yes that is a really good question, and one that is important too. In fact we currently have this under investigation. It is not something that JASP does right now (but we will in the future). Cheers, E.J.

That probably means the model is really big. The question is whether this is an issue in R as well (it probably is). I'll pass this on to our expert. Cheers, E.J.

I'll ask the expert! Cheers, E.J.

Hi Lea, Sometimes the evidence is so large that it cannot be represented on your computer. However, since you are interested in the interactions I would go to the "model" tab and add all of the main effects to the null model. Now your BFs …

Hi Sofie, The analysis of effects considers *all* models in the set; it sums the posterior probability for all models that include the effect (and then compares the posterior inclusion odds to the prior inclusion odds to obtain the inclusion BF). So…

Hi Firona, I am pretty sure JASP includes the covariate as you would in R. So your question would then be on a more conceptual level, I assume? Intuitively I've always thought of the covariates as follows: you include only the covariates, and this y…

I don't think this is possible at the moment. Would be a good feature request! I've forwarded this to our network expert. Cheers, E.J.

Feedback: there is one false alarm among many packages. We're currently struggling to get a new version out; maybe the new version will not have this issue, or maybe more people will experience the problem. We will reconsider the situation then. Tha…

That does not appear to be the case, but I'll ask our expert. E.J.

That is correct. The figure is meant to be descriptive, so it uses a flat prior (and therefore gives the same result as the frequentist confidence intervals). The complication with basing the credible interval on the model is that there are often mu…

Kruschke developed a Bayesian t-test (with the emphasis on "a"). This is not the one implemented in JASP, which is based on the work by Jeffreys. In the help file you will see a reference to Rouder et al., 2009, and Gronau et al. The assum…

I've checked and this does not ring a bell for anybody in the team. But we've added it to our list. Cheers, E.J.

Dear jmbostwick, "My understanding is that the BF01 for a given model can be roughly interpreted as the odds that the best model is a better fit than the given model. For instance, the model in Box 2 has a BF01 value of 2.064, meaning the best …

It uses metaBMA: https://www.dwheck.de/software/metabma-bayesian-model-averaging-for-meta-analysis/ Cheers, E.J.

Hi Max I'd consider group fixed in both scenarios. Cheers, E.J.

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

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

I'll forward this to our expert... E.J.

At a minimum, this is a pretty uninformative error message. Could you post this as a bug report on our GitHub page? (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/) Cheers, E.J.

Hello Shane, You are ahead of the pack! The reason that you have not found anything is because we have not rolled out this functionality. I'll talk to the team about providing a version that contains the quality control tools that we have already de…

Also, I recommend you update to 0.14.1 :-)

Hi Yuqi, We've come across these kinds of discrepancies before. Usually the Bayesian results are consistent with what you'd get from applying a frequentist linear mixed model to the data (the Bayesian RM ANOVA is really a mixed model). Also, the mo…
-
Hi Matteo, I would say that's a clear "no": the usual p-value is computed under a fixed-N sample plan, which is definitely not the one you intend to follow. What I would do instead is report the probability of obtaining misleading evidence…
-
I'm sure we'll add this in the future, but it isn't implemented in JASP at the moment. Cheers, E.J.
-
You can't, as far as I know. But I've added it to our to-do list! Cheers, E.J.
-
Hmm that is strange. We've had something like this before, when the culprit was some innocent component of an R package. We'll look into this. As an aside, this topic is better suited for our GitHub page -- I'll forward this to our programmers for n…

Hi DMcCool Sorry for the tardy response, this one slipped through the cracks. What do you mean when you say "restrict the columns"? A toy example would help. Cheers, E.J.
