摘要
文章研究了当解释变量取值在某个抽象的函数空间上时条件中位数的非参数估计,给出了基于长记忆函数型数据条件中位数的核估计,并且在一定的条件下建立了估计量的相合性,给出了基于长记忆函数型数据条件分位数的核估计量在相应条件下的相合性。
This paper studies the nonparametric estimation of conditional median when the explanatory variable takes values in certain abstract functional space. The kernel estimation is conducted by the functional data under long-memory condition and the consistency of the estimator is constructed under certain condition. Then the convergence of the kernel estimation of conditional quantile based on func- tional data under long-memorv condition is presented.
