本文对于线性函数关系EV模型定义了t-型回归估计,并对于普通线性模型和线性函数关系EV模型给出了计算t-型回归估计的EM算法,同时获得了估计的相合性,模拟结果表明由EM算法获得的t-型回归估计的表现良好.
This paper defines t-type regression estimator for the linear functional errors-in-variables (EV) models, the EM algorithm for t-type estimators in the ordinary linear model and linear functional EV model is given. Moreover, the consistency of t-type estimators for linear EV model is also obtained. Simulations are shown that performance of the t-type estimators by EM algorithm is quite well.
