Abstract:
In this paper the asymptotic behavior of robust estimates based on GM-estimators when the observations follow a regression model with random carriers and heteroscedastic errors is established. Also one-step Newton-Raphson and reweighted estimates for these models are introduced and their breakdown point is studied. Through a Monte Carlo study their performance for small samples is studied. © 2000 Elsevier Science B.V.
