Robinson Semi parametric Estimator For Treatment The Problem of Heteroscedasticity in Semi parametric Regression Model

Abstract

AbstractIn this research, Robinson semi parametric estimator has been presented to estimate semi parametric regression model in the existence problem of heteroscedasticity,We dependent on semi parametric partial linear model (PLM) which is contain on two component, one of them parametric and another nonparametric. The cross validation used to selected the bandwidth parameter. We make a comparison among four different models by using simulation technique with three value of variance and sample size.
