I ran a regression with data for clients clustered by therapist. I first estimated the regression without using thevce(clusterclustvar)option, then I re-ran it using thevce(clusterclustvar)option. In many cases, the standard errors were much smaller when I used thevce(clusterclustvar)option....

在一般情况下,损失的自由度是和固定效应的数量对应的,但是当固定效应变量也是聚类变量 (或者聚类变量范围更大) 时,我们不计算由于固定效应损失的自由度。 实际上,由于 cluster–robust standard errors 已经在相同水平上就行了调整,上述做法可以避免对固定效应的双重惩罚。当然,这并不是reghdfe命令独有的,xtreg和xti...
Bootstrap-Based Improvements for Inference with Clustered Errors The usual solution is to calculate cluster-robust standard errors that permit heteroskedasticity and within-cluster error correlation, but presume that the ... DL Miller,AC Cameron,JB Gelbach - 《Review of Economics & Statistics》 被引...

Compared to standard D-optimal designs they produce significantly smaller bias errors, allow the fitting of a larger number of higher order terms, improve the coverage of the factor space, and still have very good variance properties. ... AR Jose,DC Montgomery,DA Rollier - 《Journal of Qualit...

This presentation updates Nichols and Schaffer's 2007 UKSUG talk on clustered standard errors. Although cluster-robust standard errors are now recognized as essential in a panel data context, official Stata only supports clusters that are nested within panels. This rules out the possibility of defini...
