Hello list, I would like to know how can I use contrats in statistical analysis. I have a simple model, "one-way analysis of variance" "or two-way..." (balanced case).
I've already used the command aov (model) to get the analysis of variance, but i know that my treatment could be organized in groups, so i would like to test these groups. Example: I have 4 treatments t1, t2, t3, t4 and i would like to test (1, 1, -1, -1) and (1, -1, 0, 0) and (0, 0, 1, -1). thanks for the attention.
