Public Class TwoSampleWilcoxonSignedRankTest
	Inherits WilcoxonTest

The TwoSampleWilcoxonSignedRankTest type exposes the following members.

Constructors

	Name	Description
	TwoSampleWilcoxonSignedRankTest	Tests whether the medians of two paired samples are different.

Properties

	Name	Description
	CriticalValue	Gets the critical value for the current significance level. (Inherited from HypothesisTestTDistribution.)
	Delta	Gets the differences between the samples. (Inherited from WilcoxonTest.)
	HasTies	Gets wether the samples to be ranked contain ties. (Inherited from WilcoxonTest.)
	HasZeros	Gets wether the samples to be ranked contain zeros. (Inherited from WilcoxonTest.)
	Hypothesis	Gets the alternative hypothesis under test. If the test is Significant, the null hypothesis can be rejected in favor of this alternative hypothesis.
	IsExact	Gets whether we are using a exact test. (Inherited from WilcoxonTest.)
	NumberOfSamples	Gets the number of samples being tested. (Inherited from WilcoxonTest.)
	PValue	Gets the P-value associated with this test. (Inherited from HypothesisTestTDistribution.)
	Ranks	Gets the rank statistics for the differences. (Inherited from WilcoxonTest.)
	Significant	Gets whether the null hypothesis should be rejected. (Inherited from HypothesisTestTDistribution.)
	Signs	Gets the signs for each of the Delta differences. (Inherited from WilcoxonTest.)
	Size	Gets the significance level for the test. Default value is 0.05 (5%). (Inherited from HypothesisTestTDistribution.)
	Statistic	Gets the test statistic. (Inherited from HypothesisTestTDistribution.)
	StatisticDistribution	Gets the distribution associated with the test statistic. (Inherited from HypothesisTestTDistribution.)
	Tail	Gets the test type. (Inherited from HypothesisTestTDistribution.)

Methods

	Name	Description
	Compute(Double, Double, DistributionTail, NullableBoolean)	Computes the Wilcoxon Signed-Rank test. (Inherited from WilcoxonTest.)
	Compute(Int32, Double, DistributionTail, NullableBoolean, Boolean)	Computes the Wilcoxon Signed-Rank test. (Inherited from WilcoxonTest.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnSizeChanged	Called whenever the test significance level changes. (Inherited from HypothesisTestTDistribution.)
	PValueToStatistic	Converts a given p-value to a test statistic. (Inherited from WilcoxonTest.)
	StatisticToPValue	Converts a given test statistic to a p-value. (Inherited from WilcoxonTest.)
	ToString	Converts the numeric P-Value of this test to its equivalent string representation. (Inherited from HypothesisTestTDistribution.)
	ToString(String, IFormatProvider)	Converts the numeric P-Value of this test to its equivalent string representation. (Inherited from HypothesisTestTDistribution.)

Extension Methods

	Name	Description
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	To(Type)	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
	ToT	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
