摘要 主要研究半参数单调变系数部分线性EV模型的估计问题,提出了单调纠偏profile最小二乘估计方法,给出了模型中未知参数和单调变系数函数的估计,并在适当条件下证明了参数估计的渐近正态性和非参数单调估计的渐近性质.最后利用计算机数值模拟验证了本文所提方法的可行性及有限样本估计结果的性质. The estimators of both parameters and monotone regression function of a semiparametric monotone varying coefficient partially linear EV model are given via our monotone modified profile least square method. Some properties of the estimators are also given. Finally, simulations results show feasibility of the proposed method, and comparisons are made between the proposed method and profile least square method.
