Suppоse fоur treаtment grоups (A, B, C, D) аre to be compаred. A separate sample of individuals is collected for each treatment, and each is measured on three response variables. Let represent the variable recorded for the individual receiving the treatment. You may assume that the MANOVA model assumptions are satisfied. The following two rows of numbers represent contrast coefficients for this situation. Assuming the sample sizes are equal, verify that these contrasts are orthogonal, and find a third contrast (i.e., find its coefficients) that is orthogonal to the first two. Contrast A B C D 1 1 -1 0 0 2 1 1 -2 0
