Title: Local influence in comparative calibration models under elliptical t-distributions
Author: Galea, M
Bolfarine, H
Vilca, F
Abstract: In this paper we consider applications of local influence (Cook, 1986) to evaluate small perturbations in the model or data set in the context of structural comparative calibration (Bolfarine and Galea, 1995) assuming that the measurements obtained follow a multivariate elliptical distribution. Different perturbation schemes are investigated and an application is considered to a real data set, using the elliptical t-distribution.
