A log-likelihood ratio test for testing whether the sample mena direction is equal to some predefined one.
meandir.test(x, mu, B = 999)A matrix with the data, unit vectors.
A unit vector with the hypothesized mean direction.
A number either 1, so no bootstrap calibration is performed or more than 1, so bootstrap calibration is performed.
A list including:
The sample mean direction
The p-value of the test.
The log-likelihood ratio test is performed.
