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.
