Four Methods for Estimating Unknown Parameters in Panel Model

摘要: 本文整理了Panel模型中未知参数的四种估计方法，分别是最小二乘估计，Within估计，Between估计和两步估计。给出了四种估计方法对应的表达式，并且简单讨论了一定条件下四种估计的优良性。

Abstract: In this paper, four methods for estimating the unknown parameters in Panel model are discussed, which are least squares estimator, Within estimator, Between estimator and two-stage estimator. This paper shows the corresponding expressions of four estimation methods, and compares the advantage of four methods under certain conditions briefly.
