Subject: Error in optim(p, fun,...)
All:
I am getting an error code from the optimization function. The code is
Error in optim(p,fun.LLike, lower=low, upper = up, method = "L-BFGS-B", :
non-finite finite-difference value [0]
If I add a trace=6 option to my control list the last message before
this error is:
At X0, 0 variables are exactly at the bounds
Any ideas on where I should start would be appreciated. Tony
