Categorical Analysis seems to sit on its own and is easy to brush by. If my knowledge went a little deeper and more theoretical, I'm sure I'd see this as just another case of the Generalized Linear Model and it would all be easy. Unfortunately, that's not where I am.
(and I'm sure the CMH will work here. As I've said in other posts, this is my first time writing a book alone, and although it's my fifth, not having another person to bounce things off of makes the experience completely new.)
