Optimal robust estimators for families of distributions on the integers
Ricardo A. Maronna, Victor J. Yohai
Let F_{θ} be a family of distributions with support on the set of nonnegative integers Z_0. In this paper we derive the M-estimators with smallest gross error sensitivity (GES). We…

Consistency of M estimates for separable nonlinear regression models
Fasano María Victoria, Ricardo A. Maronna
Consider a nonlinear regression model : y_{i}=g(x_{i},θ)+e_{i}, i=1,...,n, where the x_{i} are random predictors x_{i} and θ is the unknown parameter vector ranging in a set Θ\subs…
