Residual sum of squares and multiple potential, diagnostics by a second order local approach

Inspired by Cook's (1986) assessment of local influence by studying the curvature of a surface associated with the overall discrepancy measure, this paper assesses the local influence through the curvature of the perturbation-formed surface of residual sum of squares (RSS) and multiple potential respectively. Two examples demonstrate the effectiveness of this method on identification of influential points.
