Column-wise uniformity tests for circular data
Description
Column-wise uniformity tests for circular data.
Usage
colwatsons(u)
Arguments
u
A numeric matrix containing the circular data which are expressed in radians. Each column is a different sample.
Details
These tests are used to test the hypothesis that the data come from a circular uniform distribution.
The Kuiper test is much more time consuming and this is why it not implemented yet. Once we figure out a way to
make it fast, we will incldue it.
Value
A matrix with two columns, the value of the test statistic and its associated p-value.
