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 random-effects estimator, it turns out, is a matrix-weighted average of those two results. Under the assumption that b1 really does have the same effect in the cross-section as in the time-series — and that b2, b3, ... work the same way — we can pool these two sources of in...
The mixed effects model, which is a combination of the fixed and random effects models, is also briefly described. The main message is that not all analysis of variance models are fixed effects models and that random effects require different treatment from fixed effects. The entire discussion ...

However, it is important to note that the term "fixed effects" can also refer to a broader class of models that includes both fixed and random effects. In this context, "fixed effects" refers to the part of the model that captures the average effect of the predictor variable, while "...
Random Effects Models for Combining Results from Controlled and Uncontrolled Studies in a Meta-Analysis A random effects model is used to analyze meta-analyses containing both controlled and uncontrolled studies. A noniterative estimator of the treatment effe... Z. Li,C. Begg - 《Journal of the...
The battle here -between Fixed (FE) and Random Effects (RE)- has some shortcuts that I think are interesting. (1) RE fails completly when some of the regressor is correlated with the unobservable, (2) RE has a more complex structure for unbalanced panel in compare with FE ...
