Syntax

public double GetLogLikelihoodRatio(
	double[][] input,
	double[] output,
	GeneralizedLinearRegression regression
)

Public Function GetLogLikelihoodRatio ( 
	input As Double()(),
	output As Double(),
	regression As GeneralizedLinearRegression
) As Double

input: Type: SystemDouble
A set of input data.
output: Type: SystemDouble
A set of output data.
regression: Type: Accord.Statistics.Models.RegressionGeneralizedLinearRegression
Another Logistic Regression model.

Type: Double
The Log-Likelihood ratio (a measure of performance between two models) calculated over the given data sets.

Remarks

The Log-Likelihood ratio is defined as 2*(LL - LL0).
