Properties

	Name	Description
	CriticalValue	Gets the critical value for the current significance level.
	PValue	Gets the P-value associated with this test.
	Significant	Gets whether the null hypothesis should be rejected.
	Size	Gets the significance level for the test. Default value is 0.05 (5%).
	Statistic	Gets the test statistic.
	StatisticDistribution	Gets the distribution associated with the test statistic.
	Tail	Gets the test type.

Methods

	Name	Description
	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.
	PValueToStatistic	Converts a given p-value to a test statistic.
	StatisticToPValue	Converts a given test statistic to a p-value.
	ToString	Converts the numeric P-Value of this test to its equivalent string representation. (Overrides ObjectToString.)
	ToString(String, IFormatProvider)	Converts the numeric P-Value of this test to its equivalent string representation.

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.)

Remarks

A statistical hypothesis test is a method of making decisions using data, whether from a controlled experiment or an observational study (not controlled). In statistics, a result is called statistically significant if it is unlikely to have occurred by chance alone, according to a pre-determined threshold probability, the significance level.
