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...

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...
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. ...

Both fixed effects (FE) and random effects (RE) meta-analysis models have been used widely in published meta-analyses. This article shows that FE models typically manifest a substantial Type I bias in significance tests for mean effect sizes and for moderator variables (interactions), while RE ...

When unaccounted-for group-level characteristics affect an outcome variable, traditional linear regression is inefficient and can be biased. The random- and fixed-effects estimators (RE and FE, respectively) are two competing methods that address these problems. While each estimator controls for otherwi...
