A two-way repeated ordinal analysis of variance can address an experimental design with two independent variables, each of which is a factor variable, plus a blocking variable. The main effect of each independent variable can be tested, as well as the effect of the interaction of the two factors.

WebThe philosophy of GEE is to treat the covariance structure as a nuisance. An alternative to GEE is the class of generalized linear mixed models (GLMM). These are fully parametric and model the within-subject covariance structure more explicitly. GLMM is a further extension of GLMs that permits random effects as well as fixed effects in the ...
