The TwoMatrixKappaTest type exposes the following members.

Constructors Properties Methods Name Description Compute(Double, TwoSampleHypothesis)

Computes the Z test.

(Inherited from TwoSampleZTest.) Compute(Double, Double, Double, TwoSampleHypothesis)

Computes the Z test.

(Inherited from TwoSampleZTest.) Compute(Double, Double, Double, Double, Double, TwoSampleHypothesis)

Computes the Z test.

(Inherited from TwoSampleZTest.) 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.) GetConfidenceInterval

Gets a confidence interval for the

ObservedDifference

statistic within the given confidence level percentage.

(Inherited from TwoSampleZTest.) 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

Update event.

(Inherited from TwoSampleZTest.) PValueToStatistic

Converts a given p-value to a test statistic.

(Inherited from TwoSampleZTest.) StatisticToPValue

Converts a given test statistic to a p-value.

(Inherited from TwoSampleZTest.) 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.) Top 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.) Top Remarks

The two-matrix Kappa test tries to assert whether the Kappa measure of two contingency tables, each of which created by a different rater or classification model, differs significantly.

This is a two sample z-test kind of test.
