• Hi Nicola, sorry for the late reply. Yes, JASP allows fitting repeated measures models within the mixed model interface. The analysis tries to automatically fit the maximum random effects structure that's justified by the data. However, the warnings…

• Hi daftjasp, the analysis uses sum contrast coding for categorical (nominal / factors, ordinal) predictors (in contrast to R which uses dummy encoding by default). We have also written a more detailed reply to a similar question, where we explain ho…

• Hi jcosta, a short answer is that the analysis uses sum contrast coding for categorical (nominal / factors, ordinal) predictors (in contrast to R which uses dummy encoding by default). We have also writen a more detail reply that hopefuly explains h…

• Hi Whirly123, I will try to answer the 1st question. As of now, we are using the default rstanarm priors that are autoscaled according to the predictors and response (normal distributions) and that are designed to be weakly informative - in order to…

• Hi Katharina, happy to hear about your positive experience! The analysis uses sum contrast coding for categorical (nominal / factors, ordinal) predictors (in contrast to R which uses dummy encoding by default). This scheme is used for better interpr…

• Hi Santos, it depends on what is your question. For example, if you want to test for a difference between Won and Draw condition, you can set the corresponding rows to 1 and -1. The coding symbolizes taking the estimated marginal mean in the Won con…

• Hi Guillermo, I'm happy to hear that you are intersted in the new Mixed Models analysis. The plots support only factor variables. I suspect that you have only continuous predictors in your model - these are not shown in the variable box. You can fi…
