Abstract
Let \({Y_i} = {x'_i}{\beta _0} + {e_i},1 \leqslant i \leqslant n,n \geqslant 1\) be a linear regression model. Denote by \({\hat \beta _n}\) the M-estimate of β 0, using a convex function ρ. In [1], a basic theorem (Theorem A below) concerning the weak consistency of \({\hat \beta _n}\) is established. This theorem raises further problems concerning the consistency of \({\hat \beta _n}\) . In this note, some of these questions are considered for the special cases of LAD and LS estimates, and the methods of integrals and real function theory are used.
