SkewnessModuleCoefficient: Calculation of the skewness coefficient of the modules

In VecStatGraphs2D: Vector Analysis using Graphical and Analytical Methods in 2D

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

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.

Value

The value skewness coefficient of all input modules
