Why Not Try a Robust Regression.

Abstract

There is a multitude of regression diagnostic methods available for identification. This paper discusses three: the leverage values (the diagonal elements of the least squares projection or hat matrix), the Studentized residuals, and the difference in fitted values that results from the elimination of a case (denoted DFFITS). Keywords: Mathematical models; MINITAB computer program.
