摘要 研究带固定效应的半参数变系数面板数据模型在参数部分附加约束条件下的估计问题,结合Profile最小二乘估计和岭估计,分别建立模型参数部分和非参数部分的约束岭估计量,并给出参数部分约束岭估计量的均方误差和大样本性质。 This paper studies the estimation problem of semi parametric variable coefficient panel data model with fixed effects under the additional restriction of the parameter part.Combined with the Profile least square estimation and ridge estimation,the restricted ridge estimators of the parameter part and the nonparametric part of the model are established respectively,and the mean square error and large sample properties of the restricted ridge estimators of the parameter part are given.
