Mikkel Meyer Andersen updated MATH-431:
---------------------------------------
Attachment: MATH431-patch1
I've tidied the code up a bit, made it as a patch (svn diff) and made some
tests. In my opinion, there is still too few actual function test of the
statistical test, but I'm having difficulties in matching the results with R
because of all its corrections and special cases. I'm not sure how we should
handle it. If we should coincide with the results produced by R, we basically
have to adopt all their corrections etc. Any suggestions on how we want to deal
with this?
