Hi everyone,
I have the following code for a logistic regression,
proc logistic data=have descending; class var1(ref='3') var2/ param=reference; model treatment = var1 var2; run;
In my model, the treatment one receives IS the outcome variable.
Now, some people in the data have more than one occasion of receiving treatment for the medical condition in question. There are 20,000 people and 20,500 cases. It is a very small proportion of people with a "cluster" of cases, but I would like to account for it anyway, regarding standard error estimates. Can anyone point me in the direction of the proper code?
Thanks
