additional arguments, for example complexity value, if necessary. 
The predictive partial loglikelihood measures the prediction performance of each model fitted in a boostrap sample, using the data not in this sample. Multiplying by (2) leads to a deviancelike measure, which means that small values indicate good prediction performance.
