WebTwo-way Repeated Ordinal Regression with CLMM. 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.
