cross_time-methods function

Computes the crossing survival times

## S3 method for class 'survstan'
cross_time(
  object,
  newdata1,
  newdata2,
  conf.level = 0.95,
  nboot = 1000,
  cores = 1,
  ...
)

Arguments

• object: an object of class survstan
• newdata1: a data frame containing the first set of explanatory variables
• newdata2: a data frame containing the second set of explanatory variables
• conf.level: level of the confidence/credible intervals
• nboot: number of bootstrap samples (default nboot=1000).
• cores: number of cores to be used in the bootstrap sampling; default is 1 core;
• ...: further arguments passed to or from other methods.

Returns

the crossing survival time

Examples

library(survstan)
data(ipass)
fit <- ypreg(Surv(time, status)~arm, data=ipass, baseline = "weibull")
summary(fit)
newdata1 <- data.frame(arm=0)
newdata2 <- data.frame(arm=1)
tcross <- cross_time(fit, newdata1, newdata2, nboot = 10)
