Re: st: Osius-Rojek, Stukel's goodness of fit tests for Logistic Regression

["Alexander Severinsen" <alexande@nfh.uit.no>]

Brian,

I don't have the book, but the entire Hosmer and Lemeshow Applied logistic  
regression (both first and second ed.) is replicated in Stata (and  
SAS/SPSS) at http://www.ats.ucla.edu/stat/stata/examples/. It might be  
worth a look.

Best wishes,
Alexander Severinsen
