文章的基本回归用了reghdfe,后面要使用ivreghdfe做工具变量检验,但是该命令不支持VCE(cluster)的选项,要得到聚类稳健标准误的stata命令需要怎么写? sysuse auto ivreghdfe price weight (length=gear), absorb(rep78, tol(1e-6)) cluster(rep78) 如何统计工企数据库中样本数? 3,970,421 egen group=group(id...
先撇开其他的不说,vce(cluster id)只会影响标准误等,不会影响变量的系数。 稳健性的方差协方差只是影响SE,显著性,对系数没有影响! <hr/>stata显示type mismatch r;如何处理 数据形式不匹配,转换一下数据形式,即字符型和数值型转换一下试试,用tostring 或者destring <hr/>如何把数值型变量转换为...

ssc install reghdfe reghdfe y x1 x2, absorb(id year) cluster(id) 解析:这里的 absorb(id year) 用来吸收 id 和 year 固定效应,而 cluster(id) 则是为了处理同一地区内的误差相关性。 使用技巧: 可以使用 iv 选项执行工具变量回归。 使用vce(cluster ...) 控制簇内相关的标准误。 2. estout- 结果...
如何在stata中 cluster 两个变量 SE/Robust vce(vcetype) vcetype may be conventional, robust, cluster clustvar, bootstrap, or jackknife一般是用来产生稳健标准误的常见是这样使用,vce(cluster,id),id是截面识别符
vce(cluster),xtpcseuses OLS parameter estimates, which are consistent but inefficient.xtpcseis in some sense the opposite ofregress, vce(cluster)—no within-panel correlation is allowed, only correlation among observations at the same period and in different panels.xtcpsewill allow one specific form...
