SkewnessModuleCoefficient: Calculation of the skewness coefficient of the modules

Description

This function calculates the skewness coefficient and indicates the symmetry of the distribution from a set of input modules.

Usage

SkewnessModuleCoefficient(modules)

Arguments

modules

Vector containing the values of the modules

Value

The value skewness coefficient of all input modules

Details

One way to obtain a set of modules from X and Y coordinates of the vectors is to use the LoadData function. A normal data distribution presents a skewness coefficient equal to 0.
