This function performs the Rayleigh test of uniformity.
RayleighTest3D(coord, Alpha = 0.05)
Matrix containing the values of the coordinates
Value used to obtain the Rayleigh Value from the chi-square table. The values can be 0.05, 0.025, 0.01, 0.005, 0.001, 0.0005. The default is 0.05.
This test detects a single modal direction in a sample of angles when the mean angles is unspecified. The hypothesis of uniformity is rejected if the mean module is very large. This test assumes that a larger mean module implies a more concentration around the mean, and therefore less probability that the data is uniformly distributed.
One way to get a set of coordinates X, Y and Z of the origin position and end position
(coordinates X, Y and Z of the vector) or of the colatitude and longitude, it is using the
Returns the probability value, and indicates whether or not to accept the hypothesis of uniformity.
