理解透彻FE和RE并不容易,因为这两个词本身并不够descriptive、比较笼统且具有一定的误导性。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...
According to a 2017 article, the first stage of an efficient estimator for time-invariant and rarely changing variables in finite sample panel analyses with unit fixed effects is to run a fixed-effects model to get the unit effects. The second stage is to break down the unit effects into a...
It estimates the specified model with the fixed effects estimator and corrects its small T bias (see Nickell, 1981) using a simplified but extended version of the approach presented in Everaert and Pozzi (2007). The algorithm evaluates the bias of the fixed effects estimator in a numerical ...
TitleInterpreting the intercept in the fixed-effects model AuthorWilliam Gould, StataCorp The results thatxtreg, fereports have simply been reformulated so that the reported intercept is the average value of the fixed effects. Intuition One way of writing the fixed-effects model is ...
I have some troubles calculating fixed effects in a probit model. Stata reference manual states "there is no command for a conditional probit fixed-effects model, as there does not exist a sufficient statistic allowing the fixed effects to be conditioned out of the likelihood. Unconditional fixed...
fixest: Fast and user-friendly fixed-effects estimation Thefixestpackage offers a family of functions to perform estimations with multiple fixed-effects in both an OLS and a GLM context. Please refer to theintroductionfor a walk-through.
reghdfe is a Stata package that estimates linear regressions with multiple levels of fixed effects. It works as a generalization of the built-in areg, xtreg,fe and xtivreg,fe regression commands. It's objectives are similar to the R package lfe by Simen Gaure and to the Julia package Fi...

Furthermore, the new command allows the estimation of a "true" fixed-effects model in which the inefficiency is assumed to follow a first-order autoregressive process. These features can be considered relevant from the methodological point of view because both model parameters and inefficiency ...
