Hello, I have count data of animals (here y, y1, y2...) and env. variables (x, x1, x2 ,....).
I used a glm glm(y~x1+x2+x3....) glm(y1~x1+x2+x3....) and now I would like to add the count data of other species to investigate if they might have a bigger impact than the env. variables: #x? are the selected var from the first glm run glm(y~x?+x?+y1) glm(y~x?+x?+x?+y2) .... I wonder if there is a more elegant method to do this than adding (and removing) each y by hand. thanks in advance, cheers Martin ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
