postcheck not implemented
gladomat opened this issue · comments
I know there are some functions from the rethinking package that we need to do without. I was wondering, however, if there is an implementation of postcheck which plots posterior predictions that can be validated against actual data. This is very helpful when reviewing models to see if they fit the data well or not.
You can find the function on Richard's github page. It's used, for example, on page 306 of the book, code 10.27.
Closing as this has been implemented in ArviZ
