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. -- View this message in context: http://r.789695.n4.nabble.com/question-on-optim-fn-tp3003217p3003217.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
