Spherical-spherical correlation: Spherical-spherical correlation

Description

Correlation between two spherical variables.

Usage

spher.cor(x, y)

Arguments

x

A spherical variable.

y

A spherical variable

Value

A vector including: A vector including:

Details

A very similar to the classical correlation is calcualted. In addition, a hypothesis test for no correlation is performed. Note, that this is a squared correlation actually, so negative values will never be returned.
