Dear all,

I am trying to plot hazard functions based on the Kaplan-Meier estimators. I
understand that the easy way to do this is to use :
sts graph, hazard kernel(gaussian)

I wonder how I can use twoway to do what sts graph, hazard does?

Any suggestion is welcome

Maybe you can find useful -stkerhaz-

Search on SSC Archive.

-stkerhaz- can save the hazard estimates in a file. You can then use it and plot the estimates by twoway.

The command works on a previous Cumulative Hazard estimate, e.g.:

-sts gen H = na, by(varname)

-stkerhaz , bw(#) basecha(H) outfile(namefile)


Note that in the tails of time axis -stkerhaz- use different kernel from the official command. So in this region you can see some different shape of the hazard function.

Hope this help.

Enzo








Thanks,
