SAS code for STATA stptime

Jas5 — Fri, 20 Oct 2023 01:48:22 GMT

Hi,

I need to get person-time and rate from my event time data. I can quickly get this in STATA with 'stptime' but not know what is the syntax in SAS. In STATA, I got person-time, number of failures and 95% CI.

Thanks

Can you describe what "STPTIME" does or is???

stptime calculates person-time and incidence rates. stptime computes standardized mortality/
morbidity ratios (SMRs) after merging the data with a suitable file of standard rates specified with
the using() option.

Are you talking about time-to-event data?
Check PROC LIFETEST:

Standardization of rates and risks, including computation of SMRs, is available in PROC STDRATE.
