Use this statistic to compare different models. The smaller AIC is, the better the model fits the data.
The log-likelihood functions are parameterized in terms of the means. The general form of the functions follow:
The general form of the individual contributions follows:
The specific form of the individual contributions depends on the model.
|p||the regression degrees of freedom|
|Lc||the log-likelihood of the current model|
|yi||the number of events for the ith row|
|mi||the number of trials for the ith row|
|the estimated mean response of the ith row|
