in Effect sizes & model averaged R-squared calculation for Bayesian RM Anova Comment by EJ January 27

Dear Maria, I'm sorry to hear this. When you have questions like these it is best to involve the JASP programmers. You can reach them by posting the issue on our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-b…

in Problem installing JASP Comment by EJ January 27

In general the weighting of cases (also helpful for survey work) needs to be implemented still. A poke on our GitHub page would be welcome. E.J.

in Weight cased command in JASP Comment by EJ January 27

Let's say you get a BF10 = 3. Under equal prior probabilities, this means a posterior probability of 75% for H1 vs H0. In a simulation for what you can expect from a replication, you would first sample either H1 (with probability .75) or H0 (with pr…

in "Posterior predictive" interpretation of BF versus p value Comment by EJ January 23

I suspect they are in alphabetical order. An ugly hack would be to call the conditions "Apost" and "Bpre"; if this plot them in the right order you can save the plot as a pdf and then edit out the A and B. (let us know whether th…

in Raincloud plots - paired t-test visualisation Comment by EJ January 18

(that being said, it seems to me that in order to assess collinearity a regression approach is the first thing I'd think of) EJ

in Collinearity in ANCOVA Comment by EJ January 18

Hi Alejandro, Maybe you can be a bit more specific; perhaps including a mock data set and some screenshots would help... Cheers, E.J.

in Collinearity in ANCOVA Comment by EJ January 18

Not yet, but the upcoming version (expected this month) will have a first implementation of this. E.J.

in Is it possible to export the .r code/ syntax from an analysis conducted in JASP? Comment by EJ January 9

That should be mentioned in the documentation. And you should be able to change this in the GUI...anyway, a check is to use a one-factor RM ANOVA with two levels and see whether you get the same result. E.J.

in Bayesian repeated measures ANOVA - Model Comparison vs. Analysis of effects Comment by EJ January 8

Sorry to have missed this earlier. The post was repeated later and I've answered it there. E.J.

in Repeated measures ANOVA - Model Comparison vs. Analysis of effects Comment by EJ January 5

Hi MikJ, Thanks for sticking around, and sorry I missed this. Will bring it to the attention of the group. Some quick comments: The table is probably easier to interpret if you put "best model on top". It may be even easier to interpret if…

Hi Ravi, I don't think we have this yet, but I'll ask. Cheers, E.J.

in Ordinal logistic regression Comment by EJ January 5

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

in Multigroup SEM Comment by EJ January 5

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

in Custom Contrasts in JASP RM Anova: different df calculation (and error pooling) in 0.14.1 and 0.16.3 Comment by EJ January 5

At the moment the Bayesian mixed model functionality does only parameter estimation, not null hypothesis testing Cheers, E.J.

in Testing Null Hypothesis in Bayesian Linear Mixed Model (JASP) Comment by EJ January 5

Hi Marijn, I'll ask our expert. This seems to be information that ought to be reported in the help file... Cheers, E.J.

in Default priors bayesian GLMM Comment by EJ January 5

Hi MB, We took our inspiration from the Hastie & Tibshirani book. So I would basically consult a classic text (or watch some tutorial videos on YouTube) Cheers, E.J.

in Reporting machine learning results (K nearest neighbors) Comment by EJ January 5

This is really an issue for our GitHub page, but I'll direct out programmers here. My initial guess is that this is due to the admin settings. If you can't change these, what you can do is to download and unzip the pre-installed version of JASP. E.J.

in Loading the packages of module jasp descriptives failed Comment by EJ January 3

Dear num3, This is not trivial. I believe the Rouder et al. 2009 PBR paper provides some details, and so does the Gronau et al. 2020 American Statistician paper " Informed Bayesian t-tests." (available on my website). And then there are th…

I'll pass this on to our experts E.J.

in Need more information regarding JASP model validation Comment by EJ December 2022

Not right now, but it would be a good feature request for our GitHub page! E.J.

in Back-up data for distribution plot under descriptive statistics Comment by EJ December 2022

Hi Max, Johnny van Doorn's work is relevant here (it is the basis of the implementation in JASP). The help file gives van Doorn, J., Ly, A., Marsman, M., & Wagenmakerss, E.-J. (2020). Bayesian rank-based hypothesis testing for the rank sum test,…

in Bayesian Wilcoxon signed-rank test in R Comment by EJ December 2022

We have worked hard on this, and I am happy to report that the next version of JASP will have R code integration. We hope to have a "nightly" (experimental version) with this functionality out any day now. For this particular version, the …

in Export R code Comment by EJ December 2022

Dear B_S, I suspect the computation of the CI interval for Spearman's rho requires the use of the bootstrap. Since the bootstrap is ticked off by default, no intervals are initially produced for Spearman's rho. It would be possible to have the boots…

Thanks Quentin! E.J.

in Bayesian one proportion test: different results in JASP and BayesFactor package Comment by EJ December 2022

With your sample size and design, I am not surprised that p=.041 maps on to BF01 = 10/6. I'll ask other team members about this and see what they say. Cheers, E.J.

in Understanding "Main and Interaction Effects" in Bayesian ANOVA Comment by EJ December 2022

This is a rundimentary editor. Feel free to post suggestions for enhancement on our GirHub page. You can set the scale on each axis separately. E.J.

in scale in descriptive plot Comment by EJ December 2022

That's great -- feel free to elaborate how you solved it, to help other users! I am sorry I did not get to address this issue straight away.
