TwoSampleTest<T> Class

Represents a HypothesisTest based on two samples.

Definition

Namespace: Extreme.Statistics.Tests
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
C#
public abstract class TwoSampleTest<T> : HypothesisTest
Inheritance
Object  →  HypothesisTest  →  TwoSampleTest<T>
Derived

Type Parameters

T
The element type of the samples.

Remarks

Use the TwoSampleTest<T> class as a base class for a statistical test based on two samples. This class adds the Sample1 and Sample2 properties, which can be used to get or set the samples. It also provides a constructor that allows this property to be set at the time of construction.

This is an abstract base class and cannot be instantiated directly.

Note to inheritors: You must override CalculateStatistic(). You must also set the Distribution property, either in the constructor or in your CalculateStatistic() implementation. If applicable, you should override GetConfidenceInterval(Double).

Constructors

TwoSampleTest<T>(HypothesisType) Constructs a new TwoSampleTest<T> object.
TwoSampleTest<T>(Vector<T>, Vector<T>, HypothesisType, Double, ContinuousDistribution) Constructs a new TwoSampleTest<T> object.

Properties

Distribution Gets the probability distribution used in the hypothesis test.
(Inherited from HypothesisTest)
HypothesisType Gets or sets whether the test is one or two-tailed.
(Inherited from HypothesisTest)
Name Gets the name of the hypothesis test.
(Inherited from HypothesisTest)
PValue Gets the probability that the test statistic would take on the calculated value under the alternate hypothesis.
(Inherited from HypothesisTest)
Sample1 Gets or sets the first sample this test is being applied to.
Sample2 Gets or sets the second sample this test is being applied to.
SignificanceLevel Gets the significance level used to test the null hypothesis.
(Inherited from HypothesisTest)
Statistic Gets the value of the test statistic.
(Inherited from HypothesisTest)

Methods

CalculateStatistic Evaluates the test statistic.
(Inherited from HypothesisTest)
EqualsDetermines whether the specified object is equal to the current object.
(Inherited from Object)
FinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object)
GetConfidenceInterval() Returns the confidence interval for the test parameter for the default confidence level.
(Inherited from HypothesisTest)
GetConfidenceInterval(Double) Returns the confidence interval for the test parameter for the specified confidence level.
(Inherited from HypothesisTest)
GetHashCodeServes as the default hash function.
(Inherited from Object)
GetLowerCriticalValue() Gets the lower critical value for the hypothesis test's current significance level.
(Inherited from HypothesisTest)
GetLowerCriticalValue(Double) Gets the lower critical value for the hypothesis test at the specified significance level.
(Inherited from HypothesisTest)
GetPValue Gets the probability that the test statistic would take on the calculated value under the specified alternate hypothesis.
(Inherited from HypothesisTest)
GetTypeGets the Type of the current instance.
(Inherited from Object)
GetUpperCriticalValue() Gets the upper critical value for the test statistic at the hypothesis test's current significance level.
(Inherited from HypothesisTest)
GetUpperCriticalValue(Double) Gets the upper critical value for the test statistic at the specified significance level.
(Inherited from HypothesisTest)
MemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
Reject() Returns whether the null hypothesis is rejected using the default significance level.
(Inherited from HypothesisTest)
Reject(Double) Returns whether the null hypothesis is rejected using the specified significance level.
(Inherited from HypothesisTest)
Summarize() Returns a string containing a human-readable summary of the object.
(Inherited from HypothesisTest)
Summarize(SummaryOptions) Returns a string containing a human-readable summary of the object using the specified options.
(Inherited from HypothesisTest)
ToStringReturns a string that represents the current object.
