Abstract

Regression function estimation from independent and identically distributed data is considered. The L 2 error with integration with respect to the design measure is used as an error criterion. It is shown that suitably defined local polynomial kernel estimates are weakly and strongly universally consistent, i.e., it is shown that the L 2 errors of these estimates converge to zero almost surely and in L 1 for all distributions.
