The General Linear Models Procedure (PROC GLM) of the Statistical Analysis Sistem (SAS), presents four types of sums of squares for testing hypothesis on unbalanced data. These sums of squares are obtained from estimated functions built by SAS. The used mechanisms for the building up of these four types of estimated functions are illustred and discussed with numerical examples, step by step.
