Description

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

Usage

1
2
## S3 method for class 'glmnet'
predictProb(object, response, x, times, complexity, ...)

Arguments

object

a fitted model of class glmnet.

response

response variable. Quantitative for family="gaussian", or family="poisson" (non-negative counts). For family="binomial" should be either a factor with two levels, or a two-column matrix of counts or proportions. For family="multinomial", can be a nc>=2 level factor, or a matrix with nc columns of counts or proportions.

x

n*p matrix of covariates.

times

vector of evaluation time points.

complexity

lambda penalty value.

...

additional arguments, currently not used.

Value

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