I am using the Ben bolker's R package "bbmle" to estimate the parameters of a binomial mixture distribution via Maximum Likelihood Method. For some data sets, I got the following warning messages: *Warning: optimization did not converge (code 1: ) There were 50 or more warnings (use warnings() to see the first 50)* Also, warnings() results the following: *In 0:(n - x) : numerical expression has 8 elements: only the first used 47: In beta(a, b) : NaNs produced*
I would like to know whether this is a serious issue? if so.. how can I avoid it? thank you. -- View this message in context: http://r.789695.n4.nabble.com/bbmle-Warning-optimization-did-not-converge-tp4650730.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.
