SphericalDescriptiveStatistics Class |
Provides descriptive statistic methods suited for spherical data. Since the spherical surface is embedded in Cartesian space,
the data set is provided as a list of UnitCartesian directions locating the data points on the unit sphere.
The algorithms are based on the mathematics found in "Directional Statistics" by Mardia and Jupp.

SyntaxThe SphericalDescriptiveStatistics type exposes the following members.
Methods| Name | Description | |
|---|---|---|
  | DispersionAboutPosition |
Calculates the dispersion about a given input position.
|
| MeanDirection |
Calculates the mean direction of a list of data.
|
| MeanResultantLength |
Calculates the mean resultant length of a list of data.
|
| MeanVector |
Computes the mean vector.
|
| MedianDirection(IListUnitCartesian) |
Calculates the median direction of the data by using a simplex heuristic optimizer.
The calculation method of the optimizer defaults to NormalizedSpatialMedian which minimizes the normalized spatial median function.
|
| MedianDirection(IListUnitCartesian, SphericalMedianCalculationMethod) |
Calculates the median direction of the data by using a simplex heuristic optimizer.
The optimizer minimizes the normalized spatial median function or the embedded R^3 arc distance function to compute the median.
|
| MedianDirection(IListUnitCartesian, SphericalMedianCalculationMethod, MultivariableFunctionSolverResultsMultivariableFunctionSolverIterationResults) |
Calculates the median direction of the data by using a simplex heuristic optimizer.
The optimizer minimizes the normalized spatial median function or the embedded R^3 arc distance function to compute the median.
|
| ScatterMatrix |
Calculates the scatter matrix based upon the input data.
|
| Variance |
Calculates the variance of a list of data.
