Hello All,
I'm using SAS, Version 9.2
Variables in my model:
Event: 0, 1
height: continuous
group: 0, 1 (ref=group 0)
height*group: interaction term
I currently need to estimate the OR for height by different groups
Do I do the following:
Exponentiate height to get OR for group = 0
Exponentiate height height*group to get OR for group =1
proc genmod data=temp;
class group;
model event(ref="0")=height group height*group/ link=logit dist=binomial;
estimate "height group 0" height 1 / exp;
estimate "height group 1" height 1 height*group 1/exp;
run;
I also have a model with 3 groups instead of 2.
Event: 0, 1
height: continuous
group: 0, 1, 2 (ref=group 0)
height*group1
would the code be
proc genmod data=temp;
class group;
model event(ref="0")=height group height*group/ link=logit dist=binomial;
estimate "height group 0" height 1 / exp;
estimate "height group 1" height 1 height*group 1 0 0 /exp;
estimate "height group 1" height 1 height*group 0 1 0 /exp;
run;
