    Can you post some sample code? It is hard to tell what the issues might be with just a high level description. Also, in case others cannot run your code, can you post the error message you are seeing?

    Underneath the hood in REPLV it calls REBIN and that is what does not like strings. This turns out to be kind a tricky problem, for me at least. Here is one way to do it, but there has to be a better...

    There is no test for Anderson-Darling. That being said, Shapiro-Wilk is generally seen as preferable to Anderson-Darling (as powerful, more robust). Is there a particular reason you want to use AD?
