Spatial Error Component Fay-Herriot Models for Small Area Estimation

Fay-Herriot模型已在小域估计中得到了广泛应用,进而提出一类新的空间误差分量Fay-Herriot模型用以刻画空间效应。基于所提出的模型,给出小域目标参数的经验最佳线性无偏预测估计量;同时,还给出所提估计量对应均方误差的估计,并通过数值模拟验证所提方法的有效性。

The Fay-Herriot model is widely used in small area estimation.This paper proposes a new spatial error component Fay-Herriot model to capture the spatially effects.An empirical best linear unbiased predictor(EBLUP)for small area parameters has been obtained under the proposed model,and an estimator of the mean squared prediction error of the EBLUP has also been given.Some simulations are conducted to examine the performance of the proposed estimators and the results are satisfactory.
