摘要
对未知概率密度的估计量进行了研究，并用相似的方法讨论了概率密度的一、二阶导数的估计问题。
This paper discussed problems on nonparametric estimation of unknown probability density kernel estimation. And based on this it discussed the estimations of first and second order derivations of the density similarly. The admissible weight function is also investigated and a few theorems are given.
