Hi Lewend and E.J., A couple of comments on E.J.'s implementation: 1) logit.p1 ~ dnorm(logit.p0,r): JAGS uses the precision parameterization, not the SD parameterization. 2) r <- .707: The default in proportionBF seems to be 0.5. 3) If one wants…

Dear jploenneke, With respect to E.J.'s first point: You can find the corresponding R code here. Cheers, Quentin

Hi Alon, I agree with E.J.. The Bayesian ANOVA in JASP is implemented using the Bayesian linear mixed model framework from the BayesFactor package by Richard Morey. That is, the Bayesian repeated measures ANOVA in JASP is a Bayesian linear mixed mo…

Hi Florian, I think the discrepancy for the ToothGrowth data set occurs because JASP automatically converts the fixed factors to the R type "factor" whereas in R, you need to do this manually: ToothGrowth[["dose"]] <- as.fac…

Hi Jannik, I understand, no worries! In case you can reproduce this behavior with another data set that you can share, we would appreciate if you could let us know. With respect to your question: the p-values for the standardized and unstandardized…

Hi Jannik, Looking at the output, the first thing I notice is that the regression coefficient for "Anzahl Mitarbeiter" differs between the "Stepwise" model 1 (i.e., 12.609) and the "Enter" model 1 (i.e., 12.675). Could…

Hi Jannik, Yes, you can manually calculate R-squared change: simply substract the R-squared value for the model with less predictor variables from the one for the model with more predictor variables (i.e., in your case, substract the R-squared valu…

Hi Jannik, Looking at your screenshot, it seems to me that you have specified "method = Stepwise" which is the reason why variable inclusion/exclusion cannot be changed manually but is done automatically. In case you want to have full co…

Hi Lotje, Sorry for the delayed response. With respect to your question about forward/stepwise regression: Yes, when you apply the forward method, it is theoretically possible to end up with a model that contains all variables. However, I think, t…
