Using Residual Plots to Distinguish Cases of Predictor Omission in Linear Models
Using Residual Plots to Distinguish Cases of Predictor Omission in Linear Models
Residual plots are commonly used to diagnose possible model misspecification, including predictor omission. In this paper, we present a systematic workflow for using residual plots and partial residual plots to detect and distinguish several types of model misspecification in linear models. Our workflow uses a set of four Yes/No questions …
