Great! You can skip my question about s0 though, I found where it is being used, but I still struggle with the code and convergence problem.
I also found something here http://biostat.mc.vanderbilt.edu/wiki/pub/Main/CharlesDupontStuff/newPolr.R that seems like someone tried to fix it, but with this code I get mu starting values out of range, nor do I get it right when I try to force starting values. If you got your code to work fine, you might have the answer to my problem. If you want, maybe you could post your whole *fixed-polr.R*? :-) I also can't see where the new object s0 is used in the old code? -- View this message in context: http://r.789695.n4.nabble.com/bugs-and-misfeatures-in-polr-MASS-fixed-tp3024677p4647311.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.
