cv: Function to calculate the regular (which is also biased)...

In MBESS: The MBESS R Package

Function to calculate the regular (which is also biased) estimate of the coefficient of variation or the unbiased estimate of the coefficient of variation.

Description

Returns the estimated coefficient of variation or the unbiased estimate of the coefficient of variation.

Usage

cv(C.of.V=NULL, mean=NULL, sd=NULL, N=NULL, unbiased=FALSE)

Arguments

C.of.V	Usual estimate of the coefficient of variation (C.of.V=sd/mean)
mean	observed mean
sd	observed standard deviation (based on N-1 in the denominator of the variance)
N	sample size
unbiased	return the unbiased estimate of the coefficient of variation

Details

A function to calculate the usual estimate of the coefficient of variation or its unbiased estimate.

Value

Returns the estimated coefficient of variation (regular but biased estimate or unbiased estimate.
