Class MedianTest



  • public class MedianTestextends StatisticalTest
    The median test This test can be applied to test the null hypotheses of equal medians between populations. Exact p-value is computed through U and V statistics (number of values below of the combined sample median). An asymptotic approximation to the normal distribution is also computed.
