Macro for standardizing for age in IRR SAS 9.2

chloeb — Thu, 13 Feb 2014 19:49:46 GMT

Hi,

I am currently trying to standardize IRR by age and sex. However my current version, SAS 9.2 does not have the Proc STDRATE statement. I am unsure of how I can generate standardized IRR without this procedure.

If you have a macro or know how to standardize ratios, please advise.

Thank you,

Chloe

It's a fairly simple data step calculation if you have the data. But what version of SAS/STAT are you on?

I like this paper because it has worked examples so its easy to see the logic of how to standardize your rates.

Thank you Reeza! I am currently using SAS version 9.2.

Do you have any resources for coding the standardization of incidence rate ratios? I think I understand the basic logic of standardizing by age, however, I am at loss at finding a SAS code.

Thanks again,

Chloe

If you're looking for a macro then I don't have one, but I'm sure they're out there.

Realistically, I'd just write my code, because its so straight forward. You'd have to test and decode the macro.

Here's a few options:
