R package for quasi-variances
This repository is where the CRAN package qvcalc is maintained. The package URL on CRAN is https://cloud.r-project.org/web/packages/qvcalc/index.html .
The qvcalc package provides functions to compute and display quasi-variances that often allow a more economical summary of the variance-covariance matrix for parameters in a statistical model.
The package version to be found here is the development version, snapshots of which are published periodically on CRAN. If you want to install this development version in R, then you can for example use:
