Hello! I´m doing this:
A<-optim(vv,pen.wlsv,method="BFGS") B<-optim(vv,pen.wlsv,method="Nelder-Mead") the function is the same and the initial values too the estimate values are different, very different, at the first decimal is there an error? or maybe its because of my data, or funtion to minimize? i thought that the values must be almost equal, that the big difference between the two algoritms is in the time that they use to find a solution thank u! -- View this message in context: http://r.789695.n4.nabble.com/BFGS-and-Neldear-Mead-tp3388017p3388017.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.
