If the odds are O, the associated probability is O / (O+1). JASP gives you the BF, so you would have to multiple with the prior odds yourself. Cheers, E.J.

in Correcting for multiple tests Comment by EJ April 12

BF is a ratio, so the prior probability component needs to be in ratio form too. So you multiply BF10 with p(H1)/p(H0), which in your case equals (1-.88)/.88 = 0.136, so you get 1.703 * 0.136 = 0.232. This is the posterior odds; converting this to …

JASP gives you the Bayes factor (determined in part by the width of the Cauchy); this is independent of the multiplicity correction. Then, with the BF in hand, you adjust the prior odds; multiplying the BF with the prior odds yields the posterior od…

Hi Max, For a correction I'd recommend the procedure we use for our post-hoc ANOVA comparisons. Some background literature is cited in here: https://psyarxiv.com/s56mk Cheers, E.J.

Yes (you can also try it out and see). The BFexcl and BFincl do not come with this error%, but if the individual ones have small error then so will the derivatives. E.J.

in Variability of Bayes Factors Comment by EJ April 8

Hi Nico, First, it is generally not a good idea to average BFs. For instance, averaging 1/3 and 3 does not yield 1. So averaging the log BFs would be better. In addition, the variability in ANOVA is quantified by a % error, which you can bring down …

in Variability of Bayes Factors Comment by EJ April 8

Hi Emilie, First, you can change the measurement level by clicking the ruler icon. Second, the rule that JASP uses to guess the measurement level for ordinal vs scale variables depends on the number of different values that a variable takes on. This…

in Ordinal variables not recognized Comment by EJ April 6

Hi Nik, I asked the team, and one of the members, Raoul, indicated that he had already discussed this issue with you. Is anything unclear? If you want follow-up advice it is probably best if you summarize the previous discussion first. Cheers, E.J.

I'll ask around. E.J.

in WLS weights option Comment by EJ April 5

Hi rooboxley, This issue seems better suited for our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/). However, I will make some inquiries. Cheers, E.J.

in Problems with funnel plot asymmetry p values? Comment by EJ April 5

Hi jminalee, I think this is better suited for the JASP GitHub page, which brings you into contact with the programming team. I'd also include a screenshot. For details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/ Cheers, E…

Hi Narcilili, The Bayesian ANOVA includes a "Post-hoc Tests" section that reports the t-tests, corrected using the Westfall method (see also https://psyarxiv.com/s56mk). However, I cannot reproduce your numbers -- you have 243 whereas I ge…

Hi Sofia, Yes, that is the right operation. Spearman's rho operates on the ranks; it won't work for nominal variables of course. Cheers, E.J.

I'll pass this on. E.J.

Good to hear! E.J.

in JASP Data editing? Comment by EJ April 1

If it is not there, then it would make for a good feature request! (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/) Cheers, E.J.

For closure: this was discussed on our GitHub page (it is scientific notation to help display very small numbers) E.J.

in error in displaying values in correlation matrix Comment by EJ April 1

Sorry about the delay. This is strange and unusual. The programming team would need to help you out with this; you can contact them directly through our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/)…

Hi Don, Those means are the model-averaged ones? E.J.

in Beta values Comment by EJ April 1

Hi CJM, This is a more involved modeling project. When I look at the data it does seem as if a zero-inflated Poisson model is appropriate for your data. So personally I would check out a program like brms (a wrapper for Stan) and go from there. Chee…

I've asked around, sorry about the delay.

in How to get the "goodness of fit" measure/s between two/or multiple models of mediation? Comment by EJ April 1

Hi Emily, Good point. The "plot of coefficients" gives a figure with coefficients under a range of different models, but I am not sure there is a corresponding table. There should be. Let's see what the team says. E.J.

in Beta values Comment by EJ April 1

I'll check whether this is an issue for our implementation as well. E.J.

Sorry for the tardy reply. I will forward this to the team. I know that the request to store and plot residuals is a common one... E.J.

in Plotting unstandardised residuals in JASP? Comment by EJ April 1

Somehow Excel puts everything in one column; it does not respect the comma as a field separator. I am sure you could change that setting somewhere. If you google excel use comma as separator you should get some good advice E.J.

in JASP Data editing? Comment by EJ April 1

Yes, this was a recent change in 14.1. On purpose, but it turned out to confuse a lot of people (check out our GitHub page) so we will revert to the old method in the next version. Cheers, E.J.

Howdy, Stranger!
