Dear All, I'm using a glm to analyse the effect of year on a variable with poisson distribution. Using the summary() I can test whether years are different from each other, but how can I test whether year has an overall effect on my respons variable? My guess is that by a Wald-test, but I don't know how exactly.
Could someone give me advice? Many thanks, Istvan ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
