OneSampleChiSquareTest Class

Represents a test that the population variance of a Vector<T> is equal to a specific value.

Definition

Namespace: Numerics.NET.Statistics.Tests
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.4
C# 
public class OneSampleChiSquareTest : OneSampleTest
Inheritance
Object  →  HypothesisTest  →  OneSampleTest<Double>  →  OneSampleTest  →  OneSampleChiSquareTest

Remarks

Use the OneSampleChiSquareTest class to test the hypothesis that the variance of a variable variable is equal to a specified value.

The sample data can be supplied either as a Vector<T>, or by specifying the SampleVariance and the SampleSize.

A confidence interval for the variance of the sample can be obtained using the GetConfidenceInterval(Double) method.

Constructors

OneSampleChiSquareTest() Constructs a new OneSampleChiSquareTest.
OneSampleChiSquareTest(Vector<Double>, Double) Constructs a new OneSampleChiSquareTest for the specified Vector<T>.
OneSampleChiSquareTest(Int32, Double, Double) Constructs a new OneSampleChiSquareTest for a sample with the specified parameters.
OneSampleChiSquareTest(Vector<Double>, Double, HypothesisType) Constructs a new OneSampleChiSquareTest for the specified Vector<T> with known variance.
OneSampleChiSquareTest(Int32, Double, Double, HypothesisType) Constructs a new OneSampleChiSquareTest for a sample with the specified parameters.
