• New analysis added: Frequentist/ Classical Generalized Linear Model to the Regression module (jasp-stats/jasp-issues#1656).
• ANOVA:
  • The Bayesian repeated-measures ANOVA now includes random slopes for all but the highest order repeated-measures interaction. This brings the results from the frequentist and Bayesian repeated-measures ANOVA closer together. The old behavior can be retrieved by checking Legacy results.

Custom allows for specifying individual inclusion probabilities for each effect. Note that the inclusion probabilities for interactions change if the principle of marginality is violated.
