{summclust} is an R module for cluster level measures of
leverage and influence, and further implements CRV3 and CRV3J cluster
robust variance estimators.
For an introduction to the package, take a look at its vignette.
For a quick overview of different CRV estimators, take a look at the cluster robust variance estimation vignette.
For a very detailed description of the implemented methods, in particular a discussion of the different leverage and influence metrics, see:
MacKinnon, J.G., Nielsen, M.Ø., Webb, M.D., 2022. Leverage, influence, and the jackknife in clustered regression models: Reliable inference using summclust. QED Working Paper 1483. Queen’s University.
For the Stata version of the package, see here.
You can install the development version of summclust from CRAN, GitHub and r-universe with:
# install from CRAN
install.packages('summclust')
# from r-universe (windows & mac, compiled R > 4.0 required)
install.packages('summclust', repos ='https://s3alfisc.r-universe.dev')
# install.packages("devtools")
devtools::install_github("s3alfisc/summclust")These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
