In cvequality: Tests for the Equality of Coefficients of Variation from Multiple Groups

Description

Modified signed-likelihood ratio test (SLRT) for equality of CVs, using measurement data

Usage

mslr_test(nr = 1000, x, y, seed)

Arguments

nr	numeric vector length one, number of simulation runs, default is 1e3
x	a numeric vector containing individual measurement values
y	a vector of any type containing a grouping variable
seed	optional, an integer that is the starting point used in the generation of a sequence of random numbers. Include a seed if you want reproducible output.

Value

a list with the test statistic and p-value

 y <- unlist(lapply(letters[1:5], function(i) rep(i, 20)))
