So when I have two vectors of unequal sizes with different means and different standard deviations.
One has coefficient of variation of 10% and the other 15%. Which statistical test would I use to test whether this difference is statistically significant?
I've found an R package called cvequality that uses Modified signed-likelihood ratio test (SLRT) for equality of CV, but it only works with equal sample sizes.
The same package (cvequality) includes Asymptotic test for k samples (k sample populations with unequal sized) from Feltz CJ, Miller GE (1996) An asymptotic test for the equality of coefficients of variation from k population. Stat Med 15:647–658
