The nonparametric censored regression model is y = max[c, m(x) + e], where both the regression function m(x) and the … the derivatives of an uncensored nonparametric regression. We then estimate the regression function itself by solving the … usual estimators in uncensored nonparametric regression. We also provide root n estimates of weighted average derivatives of …

censored population. We then correct the derivative for the effects of the selection bias. We propose nonparametric and … semiparametric estimators for the derivative. As extensions, we discuss the cases of discrete regressors, measurement error in …

nonparametric treatment of regression errors is permitted so that it is not necessary to be explicit about the dynamic specification …

allow for covariates to enter the unit root (or near unit root) model in a nonparametric fashion, so that our model is an … extension of the semiparametric model analyzed in Robinson (1988). It is proven that the autoregressive parameter can be … estimated at rate N even though part of the model is estimated nonparametrically. Unit root tests based on the semiparametric …
