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

The same set of data can lead to opposite conclusions, depending on whether a fixed or random effects analysis is appropriate. This article discusses differences in the assumptions, analyses, and inferences for fixed and random effects analysis of variance models. The mixed effects model, which is...
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...
