VecStatGraphs3D (version 1.6)

AllAngleStatistics: Calculation of All Statistics of the Angle.

Description

This function calculates several statistics for unit and non-unit vectors from a set of input coordinates.

Usage

AllAngleStatistics(incr, ndig=4)

Arguments

incr

Matrix containing the values of the coordinates

ndig

Integer value that indicates the decimal places. The default value is 4

Value

The value All Angle Statistics of all input X, Y and Z coordinates.

Details

One way to get a set of coordinates X, Y and Z of the origin position and end position (coordinates X, Y and Z of the vector) or of the colatitude and longitude, it is using the LoadData3D function. The statistics calculated are: Spherical Standar Error, Mean Module, Concentration Parameter, Mean Direction.
