平稳过程回归函数核估计相合的充要条件
Consistency for Kernel Regression Estimation of Stationary Processes
【摘要】 本文对一类平稳过程,在 EY2<∞下及最大相关系数ρ(n)=O(n-(1/2)(logn)-2)时,获得了回归函数递归核估计强、弱相合等价的充要条件。
【Abstract】 A recursive kernel estimation sum from i=to n Y_iK((x-X_i)/h_i)/sum from i=to n K((x-X_i)/h_i)of a regression m (x)=E(Y/X=x)calculated from asymptotically uncorrelatecl observations(X_,Y_)…, (X_n,Y_n)of a pair(X,Y)is examined.The equivalent conditions of weak and strong consistency for the estimation are given.
