I would appreciate your advice.
I have a number of outcome variables that follow Normal, Gamma or Poisson distribution. The predictor is categorical with two levels, as follows: Category 1: N=321, 9.3% of the sample Category 2: N=3145, 90.7% of the sample
I understand that unequal cell size is a problem in ANOVA/regression/GLM. How can I run GLM analyses with above-mentioned distributions and unbalanced predictor?
