Use general MANOVA to perform multivariate analysis of variance (MANOVA) with balanced and unbalanced designs, or if you have covariates. This procedure takes advantage of the data covariance structure to simultaneously test the equality of means from different responses.
Calculations are done using a regression approach. A "full rank" design matrix is formed from the factors and covariates and each response variable is regressed on the columns of the design matrix.
Factors may be crossed or nested, but they cannot be declared as random; it is possible to work around this restriction by specifying the error term to test model terms (See Specifying terms to test ). Covariates may be crossed with each other or with factors, or nested within factors. You can analyze up to 50 response variables with up to 31 factors and 50 covariates at one time.
Responses: Enter up to 50 numeric columns containing the response variables.
Model: Type the model terms that you want to fit.
