Hi all,
Any suggestion on how I can compare coefficients from different models after stccreg or stcox? I tried to use the suest and test commands but unfortunately suest is not supported.
For instance lets suppose I want to see the effect of taking a drug on the probability to get again a cancer in the same place after the operation; and on the probability to get a cancer in another place in the body after operation. How can I compare the two coefficients I get from taking the drug? For example:
stset time, failure (event==1 "cancer in the same Place")
stcrreg drug, compete (event==2)
Estimates store cancer1
stset time, failure (event==2 "cancer in another place")
stcrreg drug, compete (event==2)
Estimates store cancer2
suest cancer1 cancer 2
test [cancer1_mean]drug = [cancer2_mean]drug]
UNFORTUNATELY, I cannot do this because I get an error when I run suest (it tells me that cancer 1 was estimated with a non standard vce (robust)).
If I use stcox rather than stcrreg, yet Another error: suest is not supported after stcox.
Any suggestion on how to do this comparison?
Many many thanks
Francesco
