摘要
基于删失样本,研究α-混合序列下密度函数f(x)的核估计fn(x)的r(0<r≤2)阶相合性,并给出其r阶相合速度;证明失效率函数λ(x)的r阶相合速度.
It discussed the r-th consistency of the kernel estimation fn (x) for a density function f(x) based on censored data when the data from a strong mixing sequence, and the r-th convergence rate of fn(x) was proved. At the same time, so did the estimator of the hazard rate function f(x) corresponding with fn (x).
