Class RWGPValueFunctor calculates the G statistic for a logistic model in comparison to the intercept only model. This value has approximately a chi-squared distribution with p
degrees of freedom, where p
is the number of predictor variables. The P-value of the G statistic is returned.
This class may be used as the template parameter for the class RWLogRegModelSelector.

Given regression data, computes the G statistic by comparing the p
predictor variables in the model with the intercept only model. It returns the P-value of this statistic according to a chi-squared distribution with p
degrees of freedom.
