In the current version of JASP, I realised that it is possible to center the Cauchy distribution on a specific value , instead of zero, thereby having an 'informed' prior.
However, I am really not sure how this is done. If a previous study reported an effect size of d = 0.9, do I simply center the Cauchy distribution accordingly? What about the prior width? Can I just leave it as 0.707? Is there any other information that I need?
Thank you in advance!
