Hi Tal, Thanks for replying. (1) I am going to use cohort as a factor and (2) no, there are no strong correlation between "cohort" and the other predictors.
I am using a binomial GLM and the lack of significance of "cohort" seems it was due to one of the 11 levels (the base level) of this factor to be very scarcely represented, in other words there was just one individual of cohort 1996. I did not realize it before http://r.789695.n4.nabble.com/Can-t-find-the-error-in-a-Binomial-GLM-I-am-doing-please-help-tc4615340.html someone made me point it out. -- View this message in context: http://r.789695.n4.nabble.com/Binomial-GLM-chisq-test-or-tp4608941p4616774.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
