Dear:

I am having problem with simulation. Sometimes for 100 iteration, my
program works but sometimes give error message regarding some "built-in
function" which I never used
in my code. I have no idea about the problem. Any suggestion, comments or
idea regarding this would be highly appreciable. Thanks.

I have used ---- "maxLik()" and "BBsolve()" in my code. Error message shows
regarding "optim()".


Best regards.
