[R] (off topic) article on advantages/disadvantages of types of SS?
Hello. Please excuse this off-topic request, but I know that the question has been debated in summary form on this list a number of times. I would find a paper that lays out the advantages and disadvantages of using different types of SS in the context of unbalanced data in ANOVA, regression and ANCOVA, especially including the use of different types of contrasts and the meaning of the hypotheses that are tested in such cases. Thanks for any leads.

Bill Venables' `Exegeses on Linear Models' has very good discussions: http://www.stats.ox.ac.uk/pub/MASS3/Exegeses.pdf Andy> From: Bill Shipley > > Hello.

Hello Bill, two papers that might be of interest to you are: 1) Bill Venables's Exegesis (Google will find that for you very quickly), and 2) Nelder, J.A. 1994. The statistics of linaer models: back to basics. Statistics and Computing 4:221-134. Good luck! Andrew On Mon, Oct 04, 2004 at 08:18:48AM -0400, Bill Shipley wrote:> Hello.

Dear Bill, I discuss the matter in some detail in my text Applied Regression Analysis, Linear Models, and Related Methods (Sage, 1997) and supply a number of references there.
