| 2 | LOCAL MEDIAN ESTIMATION OF VARIANCE FUNCTION显示文摘This paper considers local median estimation in fixed design regression problems. The proposed method is employed to estimate the median function and the variance function of a heteroscedastic regression model. Strong convergence rates of the proposed estimators are obtained. Simulation results are given to show the performance of the proposed methods. | 杨瑛 W.C.Ip Y.K.Kwan P.Y.K.Kwan | 2004 | Acta Mathematica Scientia2004，24，1： | 0 |
