固定效应(fixed effect, FE)vs. 随机效应(random effect, RE)是统计学中躲不开的一对重要概念,也是统计学思想的一个非常核心的理念: 真实世界的复杂现象 = 确定的统计模型 + 不确定的随机误差 虽然在特定的统计方法中,大家或多或少能区分什么是固定效应、什么是随机效应,但是由于不同的统计方法(甚至不同的学科...
to take a single example, in their study of the role hospitals play in observed disparities in the treatment of black and white patients with acute myocardial infarction, barnato and colleagues treat hospital-level influences as a fixed effect using conditional logit models. for a range of ...
Subject: Re:st: Re: fixed effects vs random effects Hi everybody. Kit Baum suggests an instrumental variable estimator to dela with endogeneity. But in this case what is the better estimator between IVfixed effect (xtivreg2, fe) and IV first-difference (xtivreg2, fd with, optionally, gmm...
Fixed vs. Random 3 In the literature, fixed vs random is confused with common vs. varying effects meta-analysis. Common effect MA – only a single population parameter Varying effects MA – parameter has a distribution (typically assumed to be Normal) I will usually say ‘random effects’ ...
50 AM Subject: Re: Re:st: Re: fixed effects vs random effects Dear All, Thanks to all who have contributed to my query on FE vs RE as means of addressing both unobserved effect and endogeneity where regressors are less time-variant. Some comments to your suggestions are in order: Kit...

Although model-based small-area estimators are usually based on random-effects models, the assumption of fixed effects is at face value more appropriate.Model-based estimators are justified by the assumption of random (interchangeable) area effects; in practice, however, areas are not interchangeable...
