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...

The choice of the model affects the outcomes of the summary estimate. This chapter covers the key assumptions, characteristics and rationale for selection of the fixed effect and random effects model for analysis.doi:10.1007/978-3-030-71921-0_7Ravisha Srinivasjois...
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 ...

一个自变量可以同时产生fixed effect和random effect么? No! A predictor cannot simultaneously produce both random and fixed effects in the same analysis. In a multilevel model, a predictor is either treated as a fixed effect, where its effect on the outcome variable is assumed to be constant acro...

Correctly specifying the fixed and random factors of the model is vital to obtain accurate analyses. Now, you may be thinking of the fixed and random effects in the model, rather than the factors themselves, as fixed or random. If so, remember that each term in the model (factor, ...
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...
