Detailed Description
A class for bivariate correlation contigency tables, conditional probabilities, and information entropy. The p-value are calculated using R.
Given a pair of columns of interest, this class provides the following functionalities, depending on the operation in which it is executed: Learn: calculate contigency tables and corresponding discrete joint probability distribution. Derive: calculate conditional probabilities, information entropies, and pointwise mutual information. Assess: given two columns of interest with the same number of entries as input in port INPUT_DATA, and a corresponding bivariate probability distribution, Test: calculate Chi-square independence statistic and, if VTK to R interface is available, retrieve corresponding p-value for independence testing.

Member Function Documentation
| static int vtkContingencyStatisticsGnuR::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

| void vtkContingencyStatisticsGnuR::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

| static vtkContingencyStatisticsGnuR* vtkContingencyStatisticsGnuR::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkContingencyStatistics.
| virtual void vtkContingencyStatisticsGnuR::CalculatePValues | ( | vtkTable * | ) | [protected, virtual] |
Calculate p-value. This will be overridden using the object factory with an R implementation if R is present.
