Parameters

input: Type: SystemDouble
A set of input data.
output: Type: SystemDouble
A set of output data.
weights: Type: SystemDouble
The weights associated with each input vector.
regression: Type: Accord.Statistics.Models.RegressionGeneralizedLinearRegression
Another Logistic Regression model.

Return Value

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).
