SurvBoost (version 0.1.2)

predict.boosting: Boosting predict function

Description

This function predicts the hazard ratio for each subject in the input dataset.

Usage

# S3 method for boosting
predict(object, newdata = NULL, ...)

Arguments

object

output from boosting_core function.

newdata

data.frame used for prediction. Default is NULL and will use data specified for boosting algorithm.

...

ignored

Value

vector of the hazard ratio for each observation relative to the sample average.

Examples

# NOT RUN {
data <- simulate_survival_cox(true_beta=c(1,1,1,1,1,0,0,0,0,0))
formula <- as.formula("Surv(time,delta) ~ strata(strata_idx) + V1 + V2 + 
V3 + V4 + V5 + V6 + V7 + V8 + V9 + V10" )
boosting.output <- boosting_core(formula, data, rate=0.1, num_iter=500)
predict.boosting(boosting.output)
