Methods
  NameDescription
Protected methodCompute(Double, Double)
Computes the multiple matrix Kappa test.
Protected methodCompute(Double, Int32)
Computes the Chi-Square Test.
(Inherited from ChiSquareTest.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodOnSizeChanged
Called whenever the test significance level changes.
(Inherited from HypothesisTestTDistribution.)
Public methodPValueToStatistic
Converts a given p-value to a test statistic.
(Inherited from ChiSquareTest.)
Public methodStatisticToPValue

Extension Methods
  NameDescription
Public Extension MethodHasMethod
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.)
Public Extension MethodIsEqual
Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices.
(Defined by Matrix.)
Public Extension MethodToTOverloaded.
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.

Remarks

The multiple-matrix Kappa test tries to assert whether the Kappa measure of many contingency tables, each of which created by a different rater or classification model, differs significantly. The computations are based on the pages 607, 608 of (Fleiss, 2003).

This is a Chi-square kind of test.
