Arguments

object: a fitted penfit object.
newdata: new covariate matrix.
newtime: vector of follow-up times.
newstatus: vector of event indicators.
complexity: unused for fitted penfit objects; included for interface compatibility.
...: unused additional arguments.

Value

Numeric predictive partial log-likelihood.
