Abstract

Weak consistency of M-estimates of regression parameters in a general linear model is established under the condition \( {\left( {X_n^{'}{X_n}} \right)^{{ - 1}}} \to 0 \) as \( n \to \infty \), where X n is the design matrix for the first n observations. The M- estimate is obtained by minimizing the sum of (inline) where ρ is a convex function satisfying some minimal regularity conditions, and ε i is the i-th residual
