Dear R users,
When I was trying to use the function *optim* to get the MLEs, quite a few
warning messages showed up as below:
Warning in log(psi * lam) : NaNs produced
I am just wondering what does this mean? Was it something wrong with my
likelihood function or was it sth wrong with the data?
Thanks in advance.
