abstract: 'Object-oriented software for model-robust covariance matrix estimators.
  Starting out from the basic robust Eicker-Huber-White sandwich covariance methods
  include: heteroscedasticity-consistent (HC) covariances for cross-section data;
  heteroscedasticity- and autocorrelation-consistent (HAC) covariances for time series
  data (such as Andrews'' kernel HAC, Newey-West, and WEAVE estimators); clustered
  covariances (one-way and multi-way); panel and panel-corrected covariances; outer-product-of-gradients
  covariances; and (clustered) bootstrap covariances. All methods are applicable to
  (generalized) linear model objects fitted by lm() and glm() but can also be adapted
  to other classes through S3 methods. Details can be found in Zeileis et al. (2020)
