Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23

public sealed class TwoSampleZTest : HypothesisTest

Visual Basic

Public NotInheritable Class TwoSampleZTest
	Inherits HypothesisTest

C++/CLI

public ref class TwoSampleZTest sealed : public HypothesisTest

[<SealedAttribute>]
type TwoSampleZTest = 
    class
        inherit HypothesisTest
    end

Inheritance: Object → HypothesisTest → TwoSampleZTest

Remarks

Use the TwoSampleZTest class to test the hypothesis that the difference between proportions of independent samples is significant.

Constructors

TwoSampleZTest()	Constructs a new unpaired TwoSampleZTest for the specified samples.
TwoSampleZTest(Int32, Double, Int32, Double, Double, HypothesisType)	Constructs a new TwoSampleZTest for the specified samples.

Properties

Count1	Gets or sets the number of observations of the first sample.
Count2	Gets or sets the number of observations of the second sample.
Difference	Gets or sets the proposed difference between the two means.
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. (Overrides HypothesisTest.Name)
Proportion1	Gets or sets the proportion for the first sample.
Proportion2	Gets or sets the proportion for the second sample.
PValue	Gets the probability that the test statistic would take on the calculated value under the alternate hypothesis. (Inherited from HypothesisTest)
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

Equals	Determines whether the specified object is equal to the current object. (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)
GetHashCode	Serves 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)
GetType	Gets 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)
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)
ToString	Returns a string that represents the current object. (Inherited from HypothesisTest)
