Extracts the predictive partial log-likelihood from a CoxBoost model fit.
# S3 method for CoxBoost
PLL(object, newdata, newtime, newstatus, complexity, …)fitted model of class CoxBoost.
n_new*p matrix of covariates.
n_new-vector of censored survival times.
n_new-vector of survival status, coded with 0 and .1
complexity, either one value, which is number of boosting steps, or a list containing number of boosting steps in argument stepno.
additional arguments, not used.
Vector of length n_new
Used by function peperr, if function fit.CoxBoost is used for model fit.
