I have made a poisson regression by using glm. Then I want to check if I have over-dispersion in my model. I tried to use glm.diag(fit.1), but then R told me it couldn't find the function glm.diag.
Does anybody know why? Or is there an other methode to check if there is over-dispersion in my model _________________________________________________________________ [[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.
