ABSTRACT
This article describes the asymptotic properties of local polynomial
regression estimators for univariate and additive models
when observation weights are included. The implications of these findings
are discussed for local scoring estimators, a widely
used class of estimators for generalized additive models described
in Hastie and Tibshirani (1990).
Key words: backfitting, generalized additive model, asymptotic properties.
