Compute Kaplan-Meier statistics

compute_kaplan(
  dat,
  strat = "strat",
  reverse_prob = FALSE,
  rtte_conditional = TRUE,
  ci = NULL
)

`dat`	data.frame with events
`strat`	vector of stratification variables
`reverse_prob`	reverse the probability (i.e. return '1-probability')?
`rtte_conditional`	'TRUE' (default) or 'FALSE'. Compute the probability for each event newly ('TRUE'), or calculate the absolute probability ('FALSE', i.e. the "probability of a 1st, 2nd, 3rd event etc" rather than the "probability of an event happening").
`ci`	confidence interval to calculate, numeric vector of length 2
