Use the ContingencyTable class to represent a 2x2 or RxC contingency table and make inferences about the relative frequencies of the tabulated data.

Individual cells are indexed through the indexed Item[Object, Object] property.

Once the Compute() method is called, various properties are available, including the Chi-square value, the coefficient of contingency, and the Cramer V.

ContingencyTable(Matrix<Double>)	Constructs a new contingency table object from counts stored in a matrix.
ContingencyTable(ICategoricalVector, ICategoricalVector)	Constructs a new contingency table for the specified variables.
ContingencyTable(ICategoricalVector, ICategoricalVector, Vector<Double>)	Constructs a new contingency table for the specified variables.
ContingencyTable(Matrix<Double>, IIndex, IIndex)	Constructs a new contingency table object from counts stored in a matrix.

ChiSquare	Returns the chi-square value for the contingency table.
CoefficientOfContingency	Returns the coefficient of contingency of the contingency table.
ColumnCount	Gets the number of columns in the contingency table.
ColumnScale	Gets the categorical scale that contains the categories corresponding to the columns in the contingency table.
CramerV	Returns the Cramer V statistic for the contingency table.
Item[Int32, Int32]	Gets the cell at the specified position in the contingency table.
Item[Object, Object]	Gets the cell for the specified values of the categories in the contingency table.
Phi	Returns the Phi coefficient for the contingency table.
RowCount	Gets the number of rows in the contingency table.
RowScale	Gets the categorical scale that contains the categories corresponding to the rows in the contingency table.
TotalCount	Gets the total of all counts in the contingency table.

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)
GetChiSquareTest	Returns the Chi-Square test for the contingency table.
GetFisherExactProbability(Boolean, Double)	Gets the probability of Fisher's exact test for the contingency table.
GetFisherExactProbability(HypothesisType, Boolean)	Gets the probability of Fisher's exact test for the contingency table.
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetLikelihoodRatioTest	Returns the likelihood ratio test for the contingency table.
GetMantelHaenszelTest	Returns the Mantel-Haenszel Chi-Square test for the contingency table.
GetType	Gets the Type of the current instance. (Inherited from Object)
GetYatesCorrectedChiSquareTest	Returns the Yates-corrected Chi-Square test for the contingency table.
MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
ToString	Returns a string that represents the current object. (Inherited from Object)
