摘要 设{X_n,n≥1}是一LPQD序列,f(x)为其概率密度函数,基于样本X_1,X_2,…,X_n,对密度函数f(x)的核估计进行讨论,在适当条件下,利用Borel-Cantelli引理、矩不等式等证明了核密度估计的强相合性、r阶相合性. Let {Xn,n ≥ 1} be a LPQD sequence, f(x) is the probability density function, the density kernel estimator off(x) is discussed based on X1 ,X2,… ,Xn,and the strong consistency and the r-order consistency are proved by Borel-Cantelli lemma and the moment inequalities under suitable conditions.
