I think you are on your own here as it is a huge chunk to chew! 
Depending on what you really mean by linear models is also part of that 
(the Wikipedia entry is amusing). Most people probably to stats 
applications like lm in R and glm in SAS.

I do have an interest and the code I have (for logistic regression) is 
probably just as easy to rewrite.
