public class ContingencyTable
- Inheritance
- Object → ContingencyTable
Remarks
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.
Constructors
Contingency | Constructs a new contingency table object from counts stored in a matrix. |
Contingency | Constructs a new contingency table for the specified variables. |
Contingency | Constructs a new contingency table for the specified variables. |
Contingency | Constructs a new contingency table object from counts stored in a matrix. |
Properties
Chi | Returns the chi-square value for the contingency table. |
Coefficient | Returns the coefficient of contingency of the contingency table. |
Column | Gets the number of columns in the contingency table. |
Column | Gets the categorical scale that contains the categories corresponding to the columns in the contingency table. |
Cramer | 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. |
Row | Gets the number of rows in the contingency table. |
Row | Gets the categorical scale that contains the categories corresponding to the rows in the contingency table. |
Total | Gets the total of all counts in the contingency table. |
Methods
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) |
Get | Returns the Chi-Square test for the contingency table. |
Get | Gets the probability of Fisher's exact test for the contingency table. |
Get | Gets the probability of Fisher's exact test for the contingency table. |
Get | Serves as the default hash function. (Inherited from Object) |
Get | Returns the likelihood ratio test for the contingency table. |
Get | Returns the Mantel-Haenszel Chi-Square test for the contingency table. |
Get | Gets the Type of the current instance. (Inherited from Object) |
Get | Returns the Yates-corrected Chi-Square test for the contingency table. |
Memberwise | Creates a shallow copy of the current Object. (Inherited from Object) |
ToString | Returns a string that represents the current object. (Inherited from Object) |
