I have no specific knowledge of this, but Thompson's document refers to MPH.FIT, and if you google that, you get to http://homepage.stat.uiowa.edu/~jblang/mph.fitting/mph.fit.documentation.2.0.htm which tells you that to get the software, you should contact the author. And "please do not distribute", etc. You could try that, but the document is from 2007, so there is some risk that you will experience an example of the "bitrot" that CRAN was designed to avoid... -pd

Greetings Peter and Jeff, Thanks for this information. Will try these type of analyses in SAS. Sure they are doable in R, but developing a procedure is difficult. Alan Agresti gives a cookbook SAS method in An Introduction to Categorical Analysis. Thanks, James
