Title:	Generalization of Cook's Distance to Nonlinear and Nonparametric Regressions

Keywords:	Cook's distance ; Nonlinear regression ; Nonparametric regression ; Influence point
Abstract:	Cook's distance is a metric for deciding whether a particular point alone affects regression estimates much in linear regressions. We will provide a generalization of this metric to the nonlinear and nonparametric regressions. Our new metric has a simple mathematic formula, and it can be computed efficiently without fitting the case-deletion data.
