Generic function for extracting the predictive partial log-likelihood
PLL.Rd
Generic function for extracting th predictive partial log-likelihood from a fitted survival model.
Details
The predictive partial log-likelihood 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 deviance-like measure, which means that small values indicate good prediction performance.
peperr
requires function PLL.class
in case of survival response, for each model fit of class class
.
At the time, PLL.CoxBoost
is available.
