To change the default maximum number of iterations (mxit =100 for derivative based algorithm), add mxit = whatever number you want.
In most cases, you need a very good initial value! This is a real challenge in using optim(). Quite often, if the initial values is not well selected, optim() can give you nonsense estimates even the algorithm converges after number of iterations. -- View this message in context: http://r.789695.n4.nabble.com/How-can-I-fixe-convergence-1-in-optim-tp2527034p2527087.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.
