Both fixed- and random-effects models use an inverse-variance weight (variance of the observed effect size). However, given the shared between-study variance used in the random-effects model, it leads to a more balanced distribution of weights than under the fixed-effect model (i.e., small...
1. what does the between estimator actually calculate? I am only familiar with the fixed and random effects model in panel data. 2. For the estimation of the fixed effects model, I use xtreg depvar variablelist, fe. Does this command automatically take care of both the country and time ef...
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...
When some of the regressors in a panel data model are correlated with the random individual effects, the random effect (RE) estimator becomes inconsistent while the fixed effect (FE) estimator is consistent. Depending on the various degree of such correlation, we can combine the RE estimator ...
In the above model, _b[avgx1] measures the effect within the cross section, and _b[deltax1] the effect within person. The model constrains the other effects to have the same effect within the cross-section and within-person (the random-effects model). ...

There are two common assumptions made about the individual specific effect, the random effects assumption and the fixed effects assumption. Therandom effectsassumption (made in arandom effects model) is that the individual specific effects areuncorrelated with the independent variables. Thefixed effectass...
如果要在面板数据模型中加入不随时间改变的变量,只能利用面板随机效应(random effect)模型。另外,我记得Political Analysis上面发表过一篇文章可以考虑时不变变量的(非空间),你可以去搜索下。Efficient estimation of time-invariant and rarely changing variables in finite sample panel analyses with unit fixed effects...
