But if the null is already thought to be false before doing the statistical test, why are we doing a null hypothesis test?Shravan Vasishthhttps://www.blogger.com/profile/13453158922142934436noreply@blogger.comtag:blogger.com,1999:blog-21621108.post-34213548440885716442018-04-11T17:58:10.052+02:002018-04-11T17:58:10.052+02:00The assumed prior mean Pr(H0)=.92 puts a very stro...The assumed prior mean Pr(H0)=.92 puts a very strong prior the alternative hypothesis being false.

How does this change under the (probably wider-spread) assumption in many experiments that the alternative hypothesis has a higher prior probability? I guess things should change in this case, right?Daniel Schadnoreply@blogger.com
