I have a problem with stcompet when I include a "by" variable; I get an error:
unrecognized command: levels7
r(199);
This occurs even when I run the example compet_example.do:
--- begin included dialogue ---
. gen treat = _n>5000
. replace t25 = -1/.25 * log(1-uniform())
(10000 real changes made)
. replace t99 = -1/.495 * log(1-uniform()) in 5000/l
(5001 real changes made)
. replace time = min(t99,t25)
(6851 real changes made)
. replace fail = (t25<t99) + 2*(t25>=t99)
(6542 real changes made)
. replace fail = 0 if time>=2
(1567 real changes made)
. replace time = 2 if time>2
(1567 real changes made)
. stset time, f(fail==1) noshow
failure event: fail == 1

. stcompet Newci=ci,compet1(2) by(treat)

r(199);
--- end included dialogue ---
As you can see all previous commands in the do-file execute
successfully and correctly. I can find no reference in the
documentation to "levels7".
Does anyone know what might be the problem here?
I am running Stata9/SE 0.2 in Windows XP Home Edition SP2
