Hi all, I am looking to fit a logistic regression using the lrm function from the Design library. I am interested in this function because I would like to obtain "pseudo-R2" values (see http://tolstoy.newcastle.edu.au/R/help/02b/1011.html).
Can anyone help me with the syntax? If I fit the model using the stats library, the code looks like this: model <- glm(x$trait ~ x$PC1 + I((x$PC1)^2) + I((x$PC1)^3), family = binomial) What would be the equivalent syntax for the lrm function? Thanks very much in advance, ----------------------------------- Josh Banta, Ph.D Center for Genomics and Systems Biology New York University 100 Washington Square East New York, NY 10003 Tel: (212) 998-8465 http://plantevolutionaryecology.org [[alternative HTML version deleted]] ______________________________________________ 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.
