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...
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 ...
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 ...

Fixed- and random-effects models in meta-analysis. There are 2 families of statistical procedures in meta-analysis: fixed- and random-effects procedures. They were developed for somewhat different inference... Hedges,LV Vevea,L Jack - 《Psychological Methods》 被引量: 2624发表: 1998年 Fixed- ...
SubjectRe: st: fixed vs random effect model DateSun, 04 Jul 2010 12:51:05 -0400 If the Haussman test rejects random-effects, that test is telling youa random-effects approach would not produce consistent results. Andthis would be a deadly flaw. ...

There are two popular statistical models for meta-analysis, the fixed-effect model and the random-effects model. The fact that these two models employ similar sets of formulas to compute statistics, and sometimes yield similar estimates for the various parameters, may lead people to believe that ...
