seeking recommendations - SAS book - advanced regression

I'm a PhD student who is analyzing healthcare claims data - counts and expenditures. Can anyone recommend a SAS book that would help me with coding? I need to do non-linear regression, such as using a Negative Binomial or using a two-part model where you first estimate the probability of having any expenditure (maybe w a logit) and then model the expenditure, given there is any (maybe w a log transformed). It would be great if there was a book that showed the code for various models, including the procedures for model specification (e.g. figuring out what model fits the best).

Are you looking for basic or advanced?

For basic textbook-like coverage, try "SAS for Linear Models"
By Ramon C. Littell, Walter W. Stroup, and Rudolf J. Freund

If you are analyzing count data, I like "Overdispersion Models in SAS"
by Jorge G. Morel and Nagaraj Neerchal.

For an advanced book on nonlinear regression models, see "Generalized Linear and Nonlinear Models for Correlated Data" By Edward F. Vonesh.

There are also some great books on mixed models that I can suggest.

Advanced - the two you suggested sound good. Thanks much!!
