Setting uniform prior for t-test and ANOVA

Hi Dr. Wagenmakers, thanks for programming JASP and maintaining this forum!

I'm new to JASP and have a question: is there a way for me to set a uniform prior for a t-test and an ANOVA analysis, respectively?

Thank you in advance!



  • Hi Siran,

    We don't have improper uniform priors for ANOVA or t-test. You could set the scale of the Cauchy to its maximum (2, I believe); this is so spread out that your results should not differ too much from those of a uniform prior (in terms of the location and spread of the posterior distribution).
