比如,心理学家和经济学家也许会因为FE和RE的问题“打架”——心理学家可能会说“我们更推荐用随机效应模型(random-effects model)!”,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...

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...

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 ...
