Title: An application of the local influence diagnostics to ridge regression under elliptical model
Author: Labra, FV
Aoki, R
Rojas, F
Abstract: In this article, we study the effect of a minor perturbation on the ridge estimator considering the elliptical distribution for the errors. The necessary matrices for assessing the local influence under the perturbation of the explanatory variables and the scale matrix are derived. The Longley data is analyzed for illustration.
