ClassDescriptionRepresents an alternative hypothesis for a hypothesis test.Argument validation methods.Base implementation for the result of a test for significance.Implements binomial test statistics.Provide an interval that brackets a local minimum of a function.For a function defined on some interval
(lo, hi)
, this class finds an approximationx
to the point at which the function attains its minimum.This class holds a point and the value of an objective function at this point.Implements chi-square test statistics.Represents an optional adjustment that is made when a discrete distribution is approximated by a continuous distribution.Represents an assumption on the dispersion of data.Implements Fisher's exact test.Implements G-test (Generalized Log-Likelihood Ratio Test) statistics.Provide a wrapper around theHypergeometricDistribution
that caches all probability mass values.Represents a non-equal comparison between two numbers.Package private exception class with constants for frequently used messages.Computes the complementary probability for the one-sample Kolmogorov-Smirnov distribution.Computes the complementary probabilityP[D_n^+ >= x]
for the one-sided one-sample Kolmogorov-Smirnov distribution.Defines a scaled power function.Computes the complementary probabilityP[D_n >= x]
, or survival function (SF), for the two-sided one-sample Kolmogorov-Smirnov distribution.Implements the Kolmogorov-Smirnov (K-S) test for equality of continuous distributions.Result for the one-sample Kolmogorov-Smirnov test.Result for the two-sample Kolmogorov-Smirnov test.Implements the Mann-Whitney U test (also called Wilcoxon rank-sum test).Result for the Mann-Whitney U test.Implements one-way ANOVA (analysis of variance) statistics.Result for the one-way ANOVA.Represents a method for computing a p-value for a test statistic.Search utility methods.Contains the result of a test for significance.Provide support for square matrix basic algebraic operations.Implementation ofSquareMatrixSupport.RealSquareMatrix
using adouble[]
array to store entries.Define a real-valued square matrix.Utility computation methods.Implements Student's t-test statistics.Result for the t-test.Implements an unconditioned exact test for a contingency table.Compute the statistic for Boschloo's test.A container of (key,value) pairs to store candidate minima.Define the method to determine the more extreme tables.Result for the unconditioned exact test.An expandable list of (x,y) values.Implements the Wilcoxon signed-rank test.Result for the Wilcoxon signed-rank test.
