PLL.CoxBoost: Predictive partial log-likelihood for a CoxBoost model fit

In peperr: Parallelised Estimation of Prediction Error

Predictive partial log-likelihood for a CoxBoost model fit

Description

Extracts the predictive partial log-likelihood from a CoxBoost model fit.

Usage

## S3 method for class 'CoxBoost'
PLL(object, newdata, newtime, newstatus, complexity, ...)

Arguments

object	fitted model of class CoxBoost.
newdata	n_new*p matrix of covariates.
newtime	n_new-vector of censored survival times.
newstatus	n_new-vector of survival status, coded with 0 and 1.
complexity	complexity, either one value, which is the number of boosting steps, or a list containing stepno.
...	additional arguments passed to predict.CoxBoost.

Details

Used by function peperr, if function fit.CoxBoost is used for model fit.

Since CoxBoost is only suggested by peperr, install it before calling this function.

Value

Numeric predictive partial log-likelihood returned by predict.CoxBoost.
