Calculation of all statistics of the azimuths

Share:

Description

This function calculates the basic circular statistics from a sample of azimuthsseveral circular data statistics from a set of input azimuths.

Usage

1
AllAzimuthStatistics(azimuths, ndig = 4)

Arguments

azimuths

Vector containing the values of the azimuths in degrees

ndig

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

Details

One way to obtain a set of azimuths from X and Y coordinates of the vectors is to use the LoadData function.

The statistics calculated are: Mean Azimuth, Mean Module, Circular Variance, Circular Standard Deviation, Circular Dispersal, Von Mises Parameter, Kurtosis Coefficient, Skewness Coefficient.

Value

The value all azimuth statistics of all input azimuths.
