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...

I understand the basic differences between a fixed-effects and a random-effects model for a panel dataset, but what is the "between estimator"? The manual explains the command, but I cannot figure out what would lead one to choose (or not choose) the between estimator. ...
