predictProb.coxnet: Extract predicted survival probabilities from a glmnet fit

Description Usage Arguments Value Author(s) References See Also


Extracts predicted survival probabilities from survival model fitted by glmnet, providing an interface as required by pmpec.


## S3 method for class 'coxnet'
predictProb(object, response, x, times, complexity, ...)



a fitted model of class glmnet


a two-column matrix with columns named 'time' and 'status'. The latter is a binary variable, with '1' indicating death, and '0' indicating right censored. The function Surv() in package survival produces such a matrix


n*p matrix of covariates.


vector of evaluation time points.


lambda penalty value.


additional arguments, currently not used.


Matrix with probabilities for each evaluation time point in times (columns) and each new observation (rows).
