Directional statistics test of uniformity (3D)

Description

Performes the uniformity test, for the 3D case, for a set of angle measurements to determine if they come from a uniform distribution (no prefered mean direction).

Usage

dir_unif_test_3D(dir, dip, conf.level = 0.95)

Arguments

dir

A vector of dip directions measurements in degrees

dip

A vector of dip angles measurements in degrees

conf.level

Confidence level to use for the critical value (Default is 0.95, and see details section below)

Details

The options for confidence level are 0.99, 0.975, 0.95, or 0.90

Value

A list with the mean resultant length, the critical mean resultant length, and the interpretation of these values
