I am now estimating the parameters for a logit model, and trying to get the estimates by laximizing the log_likelihood. The nlm function works nicely for maximizing the -(log_likelihood) and returns the parameter estimates that minimize the static, and the gradients also, but don't have any clue how I can get the standard error for the parameters. Any help will be greatly appreciated. Thanks. ______________________________________________ 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.
