Hello STATA Community,

I am a new STATA user and I am trying to compute smooth Kaplan Meier curves. Is this possible?

After created my survival dataset with all appropriate variables, I run:
Code:
sts graph, by(kidneycan)
This produces Kaplan Meier curves but unfortunately the data center I work out of will not let me release these unless they are smoothed (because every event (i.e. drop in the graph) needs to be experienced by a certain number of people for confidentiality reasons). Smoothed survival curves still show the pattern by group, but removes the specificity of when each drop occurs. Can someone help provide syntax or instruction on how to smooth these curves?

I know how to compute smooth hazard functions but I'm really only looking to produce survival curves.

Thank you for your help.
