How to analyze MANOVA asumptions from the residual/error SSCP matrix??
Hi, In an assignment, I have carried out a two-factor 2x3 level, 3 dependent variable MANOVA using SAS. Subsequently I am to assess the MANOVA asssumptions by looking at the Error SSCP matrix (or residuals as it is stated in the asssignment).
I know how to test for the assumptions (normality, variance equality and independence), but I have no clue of how to assess anything about them simply from looking at the Error SSCP matrix. All I can infer is that theres corellation between the dependent variables and that higher numbers in the diagonal means greater variance for the variables.
This is the Error SSCP matrix:
