How to output odds ratios in Proc Genmod?

/*for continuous independent variable age*/

PROC GENMOD DATA = TEMP;

CLASS ID age ;

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

REPEATED SUBJECT = ID /TYPE = exch;

RUN;

/*for categorical independent variable gender*/

PROC GENMOD DATA = TEMP;

CLASS ID gender ;

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

REPEATED SUBJECT = ID /TYPE = exch;

RUN;

Y is binary, 0 or 1.

Thank you!!!

Use estimate statement.

PROC GENMOD DATA = TEMP;

CLASS ID gender ;

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

REPEATED SUBJECT = ID /TYPE = exch;

ESTIMATE 'GENDER EFFECT' gender 1 -1/EXP;

RUN;

Thanks so much. It's working for the categorical variable gender!

When it comes to continuous variable, how to fit it to the estimate statement?

Thank you for your great help!
