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...

effects model is: Y ij =μ + τ i +ε ij . • As in the fixed effects model, the ε ij are assumed to be i.i.d. N(0, σ 2 ). • However, unlike the fixed effects model, random effects model has treatment effects, τ i , which are random variables. • Therefore, ...
Specifically, the CRE model allows for heterogeneity in the returns to the treatment and decomposes the cross-sectional bias for each individual separately. We apply this framework to a relationship in which family specific unobservables are an acknowledged concern: the effects of birth weight on ...

R语言 random.effects 位于mgcv 包(package)。 说明 为了估计的目的,GAM 的平滑分量可以被视为随机效应。这意味着可以通过两种方式将更传统的随机效应项合并到 GAM 中。第一种方法将所有平滑转换为适合通过标准混合建模软件估计的固定和随机分量。一旦 GAM 处于这种形式,那么传统的随机效应就很容易添加,并且整个模型...
In proportionate terms, LMF entry tends to be highly concentrated in particular industries. We provide empirical evidence on this by modeling the proportions of industry entrants that are LMFs, using a panel of UK manufacturing industries. Random effects proportions models indicate the role and ...
This paper considers maximum likelihood estimation and inference in the two-way random effects model with serial correlation. We derive a straightforward maximum likelihood estimator when the time-specific component follow an AR(1) or MA(1) process. The estimator is easily generalized to arbitrary st...
