i am trying to use optim() fn in R to estimate mle of my pdf. even though I
am able to get the results, but there are always warning message, which says
that NaN produced.  I am not very sure if I should ignore these warning
message since I have got solution without error message. 
I am wondering if these message is an indicator of bad mle. 
How I can debug to get rid of these warning message?

thanks a lot.
