Directional (version 2.4)

Test for a given mean direction: Test for a given mean direction

Description

A log-likelihood ratio test for testing whether the sample mena direction is equal to some predefined one.

Usage

meandir.test(x, mu, B = 999)

Arguments

x

A matrix with the data, unit vectors.

mu

A unit vector with the hypothesized mean direction.

B

A number either 1, so no bootstrap calibration is performed or more than 1, so bootstrap calibration is performed.

Value

A list including: A list including:

Details

The log-likelihood ratio test is performed.
