Assessing local influence for elliptical linear models under equality constraints. Issue 15 (2nd August 2016) - Yang, Hu
ABSTRACT: In this article, we study the local influence for the elliptical linear regression model under equality constraints. We first obtain the parameter estimators of this model using the penalized log-likelihood function and iterative techniques. Then we obtain the diagnostics under the perturbations of constant variance, responses, and explanatory variables in the spirit of Cook (1986 ). Finally, a numerical example on the data set of the salinity of water is given to illustrate the theoretical results.
