RT Book, Section T1 Bounded Influence Regression in the Presence of Heteroskedasticity of Unknown Form A1 Delgado, Miguel A. AB In a regression model with conditional heteroskedasticity of unknown form, we propose a general class of M-estimators scaled by nonparametric estimates of the conditional standard deviations of the dependent variable. We give regularity conditions under which these estimators are asymptotically equivalent to M-estimators scaled by the true conditional standard deviations. The practical performance of these estimators is investigated through a Monte Carlo experiment.
