Abstract
Available methodologies for calculating sums of squares in analyses of variance of unequal-subclass-numbers (unbalanced) data include (i) full rank reparameterized models, (ii) “indirect” methods, (iii) the R(· | ·) notation, (iv) weighted squares of means, and (v) numerator sums of squares for testing hypotheses. These techniques are described, and relationships between them explained and illustrated. Numerical illustrations are given in the Appendix.
