Hi, everyone.
GAD package analyses complex ANOVA models with any combination of
orthogonal/nested and fixed/random factors, as described by Underwood
(1997). There are two restrictions: (i) data must be balanced; (ii)
fixed nested factors are not allowed. Homogeneity of variances is
checked using Cochran's C test and "a posteriori" comparisons of means
are done using Student-Newman-Keuls (SNK) procedure.
