Description

Get Cumulative Hazard at a Landmark Timepoint

Usage

cumhazard(
  eventRates = tibble::tibble(duration = c(3, 100), rate = c(log(2)/5, log(2)/5 * 0.5)),
  landmark
)

Arguments

eventRates

A tibble containing period duration (duration) and event rate (rate) for specified periods.

landmark

The landmark of interest to evaluate cumulative hazard.

Value

A numeric which is the cumulative hazard at a landmark timepoint.

Examples

# Piecewise exponential event rates of 0.5 for time 0-3, 0.4 for time 3-6, and 0.5 after
cumhaz <- cumhazard(eventRates=tibble::tibble(duration = c(3,3,100),rate = c(0.5, 0.4, 0.3)),
                    landmark=12)
