”,而经济学家可能会说“我们基本都用固定效应模型(fixed-effect model)!”。但实际上,在各自熟悉的知识框架下理解FE和RE,就如同“盲人摸象”,双方可能都只看到了冰山一角。正因为不同学科有着不大一致的话语体系,我们更需要从一个综合的视角来深入理解这一对贯穿了很多统计模型的基本概念——FE和RE。 本文将...

要点一 固定效应模型（FixedEffectsModel）固定效应模型是一种常见的面板数据模型，它通过在模型中加入个体和时间虚拟变量来控制个体和时间固定效应。要点二 随机效应模型（RandomEffectsModel）随机效应模型假设个体和时间固定效应是随机变量，并在模型中加入相应的随机效应项。面板数据模型的应用场景 经济研究 社会学研究 ...

Although model-based small-area estimators are usually based on random-effects models, the assumption of fixed effects is at face value more appropriate.Model-based estimators are justified by the assumption of random (interchangeable) area effects; in practice, however, areas are not interchangeable...
and the remainingS−Rparameters are assumed to be fixed. We also propose an extended version of the model that includes effects of covariates on MPT model parameters. Because the likelihood functions of both versions of the model are too complex to be tractable, we propose three numerical metho...
