Also, for small effects, you need larger sample sizes to get small p-values, wheras for big effects, you can suffice with smaller sample sizes. So, the effect size and priors are independent, but both influence the sample size you need. If that an answer to yout question?Daniel Lakenshttps://www.blogger.com/profile/18143834258497875354noreply@blogger.comtag:blogger.com,1999:blog-987850932434001559.post-14865291410518595702014-05-27T15:35:06.419-07:002014-05-27T15:35:06.419-07:00Great explanation!

One question though: since the calculation appears to rely on knowing a noncentral distribution for p(h1|d), planned effect size should play a role, yes? So is the size of the expected effect an implicit corollary of the priors? Or is it orthogonal to the priors?johannhttps://www.blogger.com/profile/16428748724803791707noreply@blogger.com
