breslow: Breslow estimator object

In penalized: L1 (Lasso and Fused Lasso) and L2 (Ridge) Penalized Estimation in GLMs and in the Cox Model

Breslow estimator object

Description

Stores one or more survival stepfunctions of the Kaplan-Meier and Breslow type.

Details

Breslow objects are generally created by the penalized function and related functions.

Slots

time:

Object of class "vector". The time points at which the function starts, jumps or ends.

curves:

Object of class "matrix". The values of the curve at each time point. Note that the function is left-continuous. Curves are stored as a matrix of dimension (\# curves) x (\# timepoints).

Methods

"["

(breslow): Coerces the object to a matrix (as as.matrix) and selects rows and/or columns.

"[["

(breslow): Selects a subset of the curves.

as.data.frame

(breslow): Returns the "curves" slot together with the "time" slot in a data.frame.

as.list

(breslow): Coerces the object to a list.

as.matrix

(breslow): Returns the "curves" slot with the "time" slot as column names.

plot

(breslow): Straightforward plotting (all curves in one plot).

show

(breslow): Summarizes the dimensions of the object.

survival

(breslow): Takes a second argument (time). Extracts the value of the survival curve(s) at any time point.
