The interpretation and assumption verification sections of this regression tutorial show you how to confirm that you’ve specified the model correctly and how to adjust your model based on the results. Specifying a regression model is an iterative process. Model specification consists of determining which predictor variables to include in the model and whether you need to model curvature and interactions between predictor variables.
