Hi, I want to look at the relationship between 2 continuous/quantitative variables while adjusting for a third continuous variable. For example: relationship between height and weight adjusted for age. As I understand it using a glm would work if I had a categorical variable (I could make age into a categories) but I am interested to know if anyone knows how I can do this analysis with out making age into categories.
Any help would be appreciated. Cheers Peter ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
