Hi SellyGer15, You can activate the "compute columns" functionality. With your variable called X, say, the code would look something like X >median(X), and this will create a column with 0 and 1's that code for whether that particular X…

The solution is here: https://github.com/jasp-stats/jasp-issues/issues/1426 We also updated our installation instructions. Cheers, E.J.

The help file refers to Morey (2008) for details. I also Googled this and also found people who believe it is prudent not to pool the error term (e.g., http://people.umass.edu/~bogartz/on_pooling_error_terms..html). I'll ask Johnny for his input. Ch…

Hi MaximumLuminis, Can you explain the difference in the pre-values through the order in which the treatments are administered? In other words, there may be a training effect, in which case you might consider adding "order" as a co-variate…

Hi TarandeepKang, This is more of an issue for out GitHub page. Anyway, I usually just download the zip file, upzip it in a folder that I created (e.g., "JASP") and then click on on the .exe file to start the program. Cheers, E.J.

One change is that we load the modules now upon activation. So when a module is first activated it will take a little longer than usual. But you are experiencing a slow-down also after that? Can you give a reproducible example? (specific data and a …

:-) thanks!

Hi Nikv, Part of it will be available as a module in the next release (0.16), which is planned for this month. We are developing this functionality in close collaboration with a large international company that is switching from Minitab to JASP, so …

Dear AMa, Thanks for reporting this. I'll pass this on and will get back to you. If you find anything else, please post it on our GitHub page as a bug report. For details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/ Cheers,…

We don't offer them yet but it is a great suggestion. I'll add it to our to-do list. Thanks! Cheers, E.J.

Dear Sameha, I'd like to get to the bottom of this, but in order to do so I strongly recommend you post the issue on our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/). That way you'll be in direct c…

Hi Maryna, Yes this is correct. Cheers, E.J.

This is really useful information, but in order for our programming team to address this effectively it would be great if you could post this on our GitHub page -- for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/ Ch…

Dear Peedikayil, These are important questions, but they are also very general -- you are effectively asking for advice on how to design a study on a complex topic that few people will have background knowledge on. In my opinion, setting this up pro…

Hi Fred, The analysis-specific help file (blue circle with "i" inside) should offer some guidance, or at least point you to this: Gronau, Q. F., Ly, A., & Wagenmakers, E.-J. (2020). Informed Bayesian t-tests. The American Statistician,…

I'll ask someone from to team to assist (I am a bit swamped right now).
-
Hi Friedrich, I think you first have to decide whether you want to use ANOVA or a linear mixed model. Cheers, E.J.
-
...although you could remove the outliers as a robustness check.
-
Yes, I'd go with the z-scores. E.J.
-
Hi Sameha, Do you mean you are unable to find this test in JASP? Cheers, E.J.
-
You can't -- JASP expects the variables to be in the columns. E.J.
-
Correct. The new version should be available this week. E.J.

Hi Mateus, There isn't, as far as I know. But most people find it relatively straightforward to interpret posterior probability. Actually, our "pizza plot" method works with posterior probabilities. See https://www.bayesianspectacles.org/l…

Hi Emma, Not at the moment in JASP, although perhaps you can with Johnny's R code -- I'll ask him. E.J.

Your conclusion for Table 2 should be the other way around. 0.106 under the null is 1/0.106 = 9.43 under the alternative. That this is support *against H0* and *in favor of H1* is also evident from the P(M|data) column. E.J.
-
Hi Emma, For the regular t-test, no MCMC is needed. In fact we try to avoid MCMC whenever we can. Not all Bayesian inference uses MCMC! However, for Kendall's tau we do use a sampling-based methodology and you are right, we don't give Rhat, and I th…

Hi Branden, At the moment you cannot change variable rows into columns using JASP. You can make this a feature request on our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/) Cheers, E.J.

JASP does not currently offer this. You could issue a feature request through our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/) Cheers, E.J.

Hi Mateus, This happens because "compare to best model" is the default setting, and the first row gives the model of reference. The BF in the first row is always 1 because the model is compared to itself. In the first table there is a smid…

Hi Sameha, No, that is not valid. These are factors and need to be treated as such. Cheers, E.J.
