simulate-methods: Simulate values from an stpm2 or pstpm2 fit

In rstpm2: Smooth Survival Models, Including Generalized Survival Models

Simulate values from an stpm2 or pstpm2 fit

Description

Given an stpm2 fit and a data-frame of new data, return simulated values

Usage

    ## S4 method for signature 'stpm2'
simulate(object, nsim=1,
        seed=NULL, newdata=NULL,
        lower=1e-06, upper=1e+05, start=NULL, ...)
    ## S4 method for signature 'pstpm2'
simulate(object, nsim=1,
        seed=NULL, newdata=NULL,
        lower=1e-06, upper=1e+05, start=NULL, ...)

Arguments

object	an stpm2 or pstpm2 object
nsim	number of simulations per row in newdata
seed	optional random number seed
newdata	list of new data. If not specified, then defaults to object@data
lower	smallest possible time
upper	largest possible time
start	left truncated entry time (assumed to be zero if NULL)
...	additional arguments (for generic compatibility)

Methods

object = "stpm2"

an stpm2 fit

Examples

set.seed(1002)
fit1 <- gsm(Surv(rectime,censrec==1)~hormon,data=brcancer,df=3)
simulate(fit1, nsim=10, newdata=data.frame(hormon=1))
simulate(fit1, newdata=data.frame(hormon=0:1))
