st: problem with -artsurv-
Hello,
I'm using the program -artsurv- which estimates sample size or power
for survival data.
When I invoke the command, as follows, using syntax confirmed by the
program's author:
. artsurv, method(l) edf0(0.5) hr(1,0.75) np(3) lg(1 2) ldf(.1;.1)
wg(1 2) wdf(.3;.1) recrt(2 0,1,0) distant(0) detail(0) onesided(0)
ni(0) tunit(1)
I get an error message:
cesf not found
r(111);
Could anyone shed some light on this?
