The breakdown point of simultaneous general M estimates of regression and scale
This article deals with the breakdown point ε* of simultaneous general M estimates (Equation presented) of the regression parameter vector θ and scale parameter σ of a linear model. A general expression for ε* is derived and its numerical values are computed for the case in which the carriers have a...

This article deals with the breakdown point ε* of simultaneous general M estimates (Equation presented) of the regression parameter vector θ and scale parameter σ of a linear model. A general expression for ε* is derived and its numerical values are computed for the case in which the carriers have a normal distribution. The numerical results show that ε* is in general much lower than the minimum of the breakdown points of (Equation presented) with σ known and of (Equation presented) with θ known. The values of ∈* for some real and simulated data sets are also given. © 1991 Taylor & Francis Group, LLC. |
