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,
Nikos
