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...
Unconditional quantile regression has quickly become popular after being introduced by Firpo, Fortin, and Lemieux (2009, Econometrica 77: 953-973) and is easily implemented using the user-written command rifreg by the same authors. However, including high-dimensional fixed effects in rifreg is quit...
在统计分析中,固定效应模型(Fixed Effects Model)是一种常用的方法,用于控制某些不可观测的因素对因变量的影响。在R语言中,我们可以使用不同的函数来实现固定效应模型,其中最常用的是plm包。 什么是固定效应模型? 固定效应模型是一种统计模型,用于控制样本中个体间固定的效应。在面板数据分析中,固定效应模型可以帮助...
This package uses theFixedEffectModels.jljulia package and theJuliaCallR library to estimate large fixed effects models in R. It is a substitute to thefelmR package. It is usually faster (seebenchmarks. I find it also to be more robust to actually converge. I use theJuliaCalllibrary to ...
R fixed.effects 提取固定效应R语言 fixed.effects 位于nlme 包(package)。 说明 这个函数是通用的;可以编写方法函数来处理特定类的对象。已经具有此函数的方法的类包括 lmList 和lme。 用法 fixed.effects(object, ...) fixef(object, ...) 参数 object 可以从中提取固定效应估计的任何拟合模型对象。 ......
In the linear mixed model (LMM), several R 2 statistics have been proposed for assessing the goodness-of-fit of fixed effects. However, the performance of these statistics has not been fully demonstrated either analytically or through simulations. We report results of simulations to asses the abi...
