Hi, I am comparing SAS commands with R. consider i want to assess the effect of one exposure(like CAT where 1 equals high and 0 equals low) and one cofounding variable (like cholesterol leve,CHL) on a diseasee variable (like CHD). In SAS to get a numerical value for the odds ratio, consider, for example, the specific values CHL equal to 220 and HPT equal to 1 when the model contains interaction terms like (CC=CAT*CHL) the command is:
PROC GENMOD data=l2 DESCENDING; MODEL CHD=CAT CHL CC/LINK=LOGIT DIST=BINOMIAL; ESTIMATE CAT 1 CC 200 /EXP; RUN; I just want to find such a command in R. Its not a homework.
