How to output odds ratios for continuous variable in Proc Genmod

peppapig — Mon, 10 Feb 2014 15:22:01 GMT

PROC GENMOD DATA = TEMP;

CLASS ID ;

MODEL Y (EVENT = '1') = age /dist=bin link = ? logit;

REPEATED SUBJECT = ID /TYPE = exch;

ESTIMATE 'age' age 30.5 / exp;

RUN;

This code does have output of exp(age), L'beta estimate.

But I do not know what value to use for age in the ESTIMATE statement, mean age??

Thank you!!!

The exp(age) is your odds ratio, for every year increase in age...etc.

If you're using a specified age then that's different than the standard odds ratio.

Concerning the mean you included, is it the mean age of cases or controls or the entire dataset?
