摘要
考虑变系数多维线性结构关系EV模型y=xTβ(t),Y=y+ε,X=x+u,利用文[4]构造的参数β(t)在t=t0处的参数β(t0)的估计量βn(t0)构造参数σ2的估计量σn2,并证明它具有渐近正态性.
In this paper, we consider the estimation δn^2 of parameters δ^2 in the multivariate varying - coefficients structuralEVmodels y=x^Tβ(t),y=y+ε,X=x+u . The estimation an z are constructed by using the weighted M - estimation βn (t0) of parameters β(t) at t = t0. The asymptotic normality of estimator is also obtained
