In this paper, we present a bivariate linear mixed model including … WebOne of the main selling points of the general linear models / regression framework over t-test and ANOVA is its flexibility. We saw this in the last chapter with the sleepstudy data, which could only be properly handled within a linear mixed-effects modelling framework. Despite the many advantages of regression, if you are in a situation where you have …
