Consistency of Generalized M-Estimators

Zaman, Asad

Abstract

The consistency of M-estimators in a very general setup is proven under weak assumptions. A one-dimensional result using a quasiconvexity assumption is obtained and applied to get a result on consistency of redescending M-estimators. A result valid in higher dimensions is obtained using a law of large numbers for semicontinuous function-valued random variables. This is applied to minimum absolute deviation regression.

Additional Information

I would like to thank Professor Robert L. Taylor for guiding me through Banach space versions of the law of large numbers.
