This means we should make grid for the parameters instead of xAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3240271627873788873.post-45754153939126667782018-01-11T23:36:39.104-05:002018-01-11T23:36:39.104-05:00Yes, Stan.

It links to a preprint titled "Outgrowing the Procrustean Bed of Normality: The Utility of Bayesian Modeling for Asymmetrical Data Analysis" and the manuscript is about skew-normal distributions estimated by Bayesian methods.John K.
