Optimal smoothing for a computationally and statistically efficient single index estimator

Xia, Yingcun; Härdle, Wolfgang Karl; Linton, Oliver - 2009

In semiparametric models it is a common approach to under-smooth the nonparametric functions in order that estimators of the finite dimensional parameters can achieve root-n consistency. The requirement of under-smoothing may result as we show from inefficient estimation methods or technical...
