Tests for the Equality of Coefficients of Variation from Multiple Groups

Contains functions for testing for significant differences between multiple coefficients of variation. Includes Feltz and Miller's (1996) asymptotic test and Krishnamoorthy and Lee's (2014) modified signed-likelihood ratio test. See the vignette for more, including full details of citations.

cvequality: A package of tests for the equality of coefficients of variation from multiple groups

This package contains functions to test for significant differences in coefficients of variation (CVs) among multiple groups of observations.

To install the package:

if (!require("ghit")) install.packages("ghit") # check if you have ghit (to install pkgs from github), if not, it will be installed here

Please see the vignette for detailed examples of how to use the functions in this package.
