Hi Martin, I'll ask the expert in our team. We are nearing a new version, so it would be great to see this fixed (if it is a bug). Cheers, E.J.

Hi danke147, You can get the 95% credible interval if you click on "prior and posterior plot". I agree it's not optimal though. Ideally we report this in a table, and allow the user to set the %. I'll make a GitHub issue for this. Cheers, E.J.

Hi Max, I'll direct your question to our metaanalysis expert. Just for my own education: what exactly do you mean with "dependency"? Cheers, E.J.

Let me ask those in the know... E.J.

I'll attend our team to this. Cheers, E.J.

Also note that the null model and the factor1only model are both doing very poorly. So here it would be more informative to look at the inclusion BF for factor 1, which also takes into account more plausible models. As you can see though, the inclu…

Oh, I forgot: Joris is on safari, so let's hope he returns in one piece to answer your question E.J.

Hi Francesca For these kinds of technical issues I usually recommend our GitHub page, but it's interesting and so I'll give a preliminary response here. First, I think we don't want to make this too easy, as tossing away data is a decision that r…

Hi Tanto, We can help you out but our programming team will probably need some more information. In order to help you effectively please post the issue on our GitHub page (for details see https://jaspstats.org/2018/03/29/requestfeaturerepo…

Dear jploenneke, * "I am unaware of how to add in an informed prior (not centered on zero) to a paired ttest in R." I'll ask Quentin whether he has R code available (based on https://arxiv.org/pdf/1704.02479.pdf). Not sure whether Richard has …

I've asked around but will do some with more emphasis now. Sorry for the tardiness

Yes, the uncorrected BF needs to be multiplied by the prior odds to give the posterior odds. The correction for multiplicity is in the prior odds. As an aside, Tim's thesis is now on PsycArXiv: https://psyarxiv.com/s56mk/ Tim will do a blog post…

No, but thanks for reminding me! I'll see whether I can get that project back on track E.J.

Hi Stats We are working on some radical panel redesign that should make the analysis of interest much easier to find. I am not sure about the ordering, but perhaps that could work. You could suggest it on our GitHub page (for details see https://…

Hi Amsa, Thanks for reporting this! I think you forgot to attach the screenshot. Also, if order to detect whether there is a bug, and then fix it, it would be really great if you could report this on our GitHub page (for details see https://jasp…

JASP opens: .jasp. .csv, .ods, .txt, and .sav files. So if you have an excel file it is best to save it first as a .csv file, for instance, and then open it in JASP. Cheers, E.J.

Hi Boo, If the data are exchangeable between pilot, Exp1, and Exp2 (a big if!), then you can just label all of that data as "condition A" and compare it to "condition B" (for an unbalanced test, but that's OK). It is difficult to do things oth…

Hi Jamie This may take a while. The BRMS package may do this, but it is not set up to do Bayes factor tests. I am not aware of any formal developments for Bayes factor MANOVAs, unfortunately. Then again, to paraphrase Lord Rutherford: "if your ex…

It is a matter of taste, imo

I'd report both and acknowledge the uncertainty. Generally it is a good idea to include more knowledge. In particular, if the observed interaction is qualitatively consistent with the predicted interaction, this should help the model with the intera…

Dear AnnalenaB, Thanks for this interesting and very relevant question. I believe the Bayesian directional test makes complete sense. Suppose we start by testing the point H0 (the skeptics' position: d=0) against the twosided alternative H1 (the…

Hi Stats, I appreciate the sentiment. To an outsider, this must make a strange impression indeed. Let's just say that, if it had been up to me, this situation would never have arisen, and it took me completely by surprise. For a few years now, br…

Thanks Sebastiaan. Coincidentally, our lead programmer, Bruno Boutin, is French so if there is a desperate need for communication in French we can oblige. Cheers, E.J.

Hi Felipe, That suggests to me even more that it is an issue with the way the data are read in. But we'll see I guess. Please keep us posted! E.J.

Hi Arran, This is reasonable. Also, this distribution is close to several others that we have elicited from experts. For instance, it is similar to the "Oosterwijk prior" (see the informed ttest paper by Quentin Gronau, Alexander Ly, and myself)…

Hi Peter, I'll ask Johnny for more information on these tests. They come from R packages, and I think we've checked them against results from other programs, but Johnny knows more about that. Nice project, by the way! Cheers, E.J.

Hi Irepet, What appears to be the case is that every row (subject) shows an effect of about the same size, say like this: 1 200 300 2 700 800 3 400 500 If you drop the repeated measures aspect the results will have sufficient noise/…

Hi Stats, Jamovi is a project that was set up by some of the people who were hired to help out with the initial implementation of JASP. The reasons for why Jamovi has started at all are a little mysterious  I certainly never understood it. You …

Baby steps! Still very much on our radar though E.J.

Hi Boo, I gather that you used the pilot data for the BF ttest for Experiment 1. If you use the updating method, then you ought to use the knowledge after Experiment 1 for the analysis of Experiment 2. This knowledge includes the pilot data. So …
