Hi I conducted a binomial GLM (with 3-factor) but I need to make a contrasts test between the averages of the treatments; I need know what treatment are equal. I know that the contrasts are used only in ANOVA I suppose that is incorrect doing this in a glm, there is some way to make contrasts multiples (like tukey) for GLM? I find in the red that the function esticon is a contrasts test for GLM but I don't know in what library find this. I hope you can help me Susana [[alternative HTML version deleted]]
