CoefficientOfVariation

As of Version 7.0, CoefficientOfVariation has become a property of LinearModelFit.

is a possible value for the RegressionReport option for Regress and DesignedRegress which represents the coefficient of variation.

Details and Options

To use CoefficientOfVariation, you first need to load the Regression Common Functions Package. You can do this by using Needs["LinearRegression`"], which will automatically load the Regression Common Functions Package, or you can load the package directly by using Needs["RegressionCommon`"].
The coefficient of variation is the ratio of the response mean to the estimated standard deviation.

Wolfram Language code: Needs["LinearRegression`"]

Sample data:

Wolfram Language code:

data = {{0.05, 90}, {0.09, 95}, {0.14, 110}, 
{0.17, 125}, {0.2, 140}, {0.21, 150}, 
{0.23, 175}, {0.25, 190}, {0.3, 210}, 
{0.35, 255}};

CoefficientOfVariation for a linear regression:

Wolfram Language code: Regress[data, {1, x ^ 2}, x, RegressionReport -> {CoefficientOfVariation}]
