predictSurvProb.orsf: Compute predictions using an oblique random survival forest.

In obliqueRSF: Oblique Random Forests for Right-Censored Time-to-Event Data

Compute predictions using an oblique random survival forest.

Description

Compute predictions using an oblique random survival forest.

Usage

## S3 method for class 'orsf'
predictSurvProb(object, newdata, times, ...)

Arguments

object	A fitted model from which to extract predicted survival probabilities
newdata	A data frame containing predictor variable combinations for which to compute predicted survival probabilities.
times	A vector of times in the range of the response variable, e.g. times when the response is a survival object, at which to return the survival probabilities.
...	Additional arguments that are passed on to the current method.

Value

A matrix of survival probabilities containing 1 row for each observation and 1 column for each value in times.

Examples

## Not run: 
data("pbc",package='survival')
pbc$status[pbc$status>=1]=pbc$status[pbc$status>=1]-1
pbc$id=NULL
fctrs<-c('trt','ascites','spiders','edema','hepato','stage')
for(f in fctrs)pbc[[f]]=as.factor(pbc[[f]])
pbc=na.omit(pbc)

orsf=ORSF(data=pbc,ntree=30)
times=seq(365, 365*4,length.out = 10)

predict(orsf,newdata=pbc[c(1:5),],times=times)

## End(Not run)
