This … NettetWe will prove that the linear mixed model and the paired t-test are exactly the same model. Suppose we have \(i\) subjects and two conditions, labeled 1 and 2. For now, assume that each subject sees each condition only once (e.g., the by-subjects aggregated English relative clause data), so we have two data points from each subject.

NettetAnalysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means. … NettetThe Linear Mixed Models procedure is also a flexible tool for fitting other models that can be formulated as mixed linear models.
