Re: st: Re: Monte Carlo Simulation, help!
Hi
I have tried the following commande:
simulate mean=r(mean) var=r(Var), reps(10000): lnsim, obs(100)
from STATA help and for Inst. F
my command was:
simulate mean=r(mean) var=r(Var), reps(10000): lnsim, obs(273) mu(71) sigma(2.7%)
and I got the following error:
loc not found
an error occurred when simulate executed lnsim
r(111);
When it resolved I should run the analysis for all INSs and the mean?
the SE in the floowing table was SD.
I have copied the table again.
Many thanks for any comment
