The internal norm measure DI(C−1k) introduced in Gray (1989) assesses the influencethat a size- subset of cases has on the least squares parameter estimates in a linear regression. The term internal norm refers to the fact that the assessment of influence is based on a comparison of the subset of interest to all size- subsets internal to the data set. Although this approachis intuitively
