مستخلص: Abstract: In this paper, under a nonparametric regression model, we introduce two families of robust procedures to estimate the regression function when missing data occur in the response. The first proposal is based on a local -functional applied to the conditional distribution function estimate adapted to the presence of missing data. The second proposal imputes the missing responses using the local -smoother based on the observed sample and then estimates the regression function with the completed sample. We show that the robust procedures considered are consistent and asymptotically normally distributed. A robust procedure to select the smoothing parameter is also discussed. [Copyright &y& Elsevier]
