logistic regression with repeated measures for species-habitat associations
...8 0 1 1 1 0 0 0 5 SN seasonal 2406 90 0 1 1 1 0 1 . . . etc. So far I've analyzed each year individually using (example for 2004): newts2004 <- glm(newts ~ ., data=ponds2004, family="binomial") step(newts2004) I'd like to do a holistic analysis for all three years but am unclear how to do logistic regression with repeated measures in R. Also not sure if missing data (from dry ponds) will be a problem. Thanks very much for any advice. Cheers, Maureen...
