WebJan 15, 2015 · The typical way to perform a linear regression would be to model y as. y = X B + ϵ. where an intercept may or may not be included in the matrix of predictors. I thought about an alternative model, in which the difference in y for pairs of cases is regressed on … WebCompare this to the fixed intercept \(\beta_0\) in the simple linear model that corresponds to the unpaired t-test. In the linear mixed model, the intercept term is different for each subject because of the \(u_{0i}\) term. Let’s check that the linear mixed model delivers exactly the same t-value as our paired t-test above.
