I have a retrospective cohort study and I need to calculate incidence of disease within the population. I have time of first case and then also number of outcomes. Is there any easy way to calculate incidence with this information?

I'm not sure that's the correct procedure as I'm not trying to standardize the rate between two populations. Is there another similar procedure?

I believe proc std rate will also give you the crude rate, which is essentially the incidence rate.
You don't need a proc for this, its a simple data step, but you do have to have your data in an appropriate format. So, if you need help with the data step, you should post a sample of what your data looks like and the output you need.
