The qvcalc package provides R 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.

Full package documentation, including version history, can be viewed at https://davidfirth.github.io/qvcalc .

For more details on the statistical method, see the references below.

The web page at http://warwick.ac.uk/qvcalc gives information also about an online calculator implemented in JavaScript, for those who do not use R.

To install the package from CRAN (in R):

install.packages("qvcalc")
