Yes I did, but it wasn’t really insightful. Both the algorithms document in SPSS and the corresponding references assume a lot of pre-knowledge from the part of the reader (or at least more pre-knowledge than I have). Besides, I think it would be more helpful if someone explained it to me at a conceptual level, rather than at the technical level, like the algorithms document does. In other words: per effect, what other effects (covariates, factors, interactions among covariates, interactions among factors, interactions between covariates and factors) does the type-II sum of squares correct for?

Did you consult with the SPSS Algorithms document? It is found in Help  menu and, as pdf file, somewhere in the intallation folder.
