public class CDTest
extends StatisticalTest

The Charkraborti and Desu test (CD test) This test can be applied to test whether the median of several populations are equal or greater than the median of a control. The null hypotheses states equal medians, whereas alternative means that at least one median is greater than the control one. P-values are computed through the exact distribution of the test. A normal distribution approximation, with continuity correction, is also provided. All samples must have the same number of elements.
