摘要
设(X1,Y1),…,(Xn,Yn)是来自二元总体(X,Y)的样本,若EY<∞,则回归函数m(x)=E(Y|X=x)存在.在本文中,考虑m(x)的改良核估计:其中 K是一元概率密度, 0< hn→ 0; 0< bn→∞(n→∞)我们分别在i.i.d.和平稳φ-mixing相依情况下,得出了mn(x)的渐近分布.
Suppose that (X1, Y1),…, (Xn, Yn) is a random sample sequence from (X, Y), If EY is finite, the regression function m (of Y on X) is defined by m(x) = E(Y|X = x). In this paper, we obtain the asymptotic normality of the improved kernel regression function estimates Where K is a univariate density function, 0 < hn → 0 and 0 < bn → ∞ (n - ∞).
