javanpst.tests.oneSample.confidenceQuantile.ConfidenceQuantile

public class ConfidenceQuantile
extends StatisticalTest

A test for estimating population quantiles. This test estimates a population quantile providing a confidence interval as closer as possible. It does Two confidence intervals are provided: an exact version, using the Binomial distribution, and an approximate interval, using the Normal distribution.
