GLM Hypothesis Testing - Contained Effects
The following descriptions will use the term contained effect. An effect E1 (e.g., A * B interaction) is contained in another effect E2 if:
- Both effects involve the same continuous predictor variable (if included in the model; e.g., A * B * X would be contained in A * C * X, where A, B, and C are categorical predictors, and X is a continuous predictor); or
- E2 has more categorical predictors than does E1, and, if E1 includes any categorical predictors, they also appear in E2 (e.g., A * B would be contained in the A * B * C interaction).
