不连续密度函数 NN-估计的收敛速度

The Corvergence rate of NN-estimation for Discontinuous Density Function

讨论不连续密度函数最近邻估计（ＮＮ－估计）的收敛速度。由于密度函数不连续时的ＮＮ－估计不是相合的，我们提出一个改进的ＮＮ－估计，使之有相合性，且收敛速度不变。

This paper discusses the convergence rate of kernel estimators (NN-estimation) for discontinuous function.Because NN-estimation is not congruent when density function is discontinuous,we give an improved NN-estimation so that it has congruence and the same convergence rate.
