To someone who could help me: I am a PhD student, working in the Novosibirsk University, Russia. I am now using glm() function to do logistic regression analysis. I cannot understand how the chosen reference group. For example, for the three genotypes of GG, GC, CC I want to be risk assessed in relation to the genotype CC, but the program selects the genotype GG. How do I change the reference group?
Thanks for your time. Best wishes, Ekaterina Kudryavtseva PhD student, Department of Molecular Biology Novosibirsk University Tel: +7-923-185-82-47 _______________________________________________ R-sig-Epi@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-sig-epi
