Hi, I got a problem with polr function a bit. I have this error:
attempt to find suitable starting values failed I wonder what would be an appropriate way to solve this problem? I can try to specify some random starting value but I am afraid that it will cause the MLE to stuck at some local maxima. Is there anyway to cope with this in a more elegant way? Any help would be really appreciated. Thank you. - adschai ______________________________________________ [email protected] 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.
