frailtypack (version 2.2-12)

plot.additivePenal: Plot Method for an Additive frailty model.

Description

Plots estimated baseline survival and hazard functions of an additive frailty model, more generally of a class `additivePenal' object. Confidence bands are allowed.

Usage

## S3 method for class 'additivePenal':
plot(x, type.plot = "hazard", conf.bands=TRUE, ...)

Arguments

x

An fitted additive frailty model (output from calling additivePenal function).

type.plot

a character string specifying the type of curve. Possible value are "hazard", or "survival". The default is "hazard". Only the first words are required, e.g "haz", "su"

conf.bands

logical value. Determines whether confidence bands will be plotted. The default is to do so.

Other graphical parameters

Value

• Print a plot of HR and survival function of a class additivePenal object

Examples

data(dataAdditive) 
  modAdd<-additivePenal(Surv(t1,t2,event)~cluster(group)+var1+slope(var1),
                 correlation=TRUE,data=dataAdditive,n.knots=8,kappa1=862)

# It takes around 4 minutes to converge. 'var1' is boolean as a treatment variable. #
