observed_vs_expected_mortality: Calculate observed vs expected mortality

In ampel-leipzig/ameld: Data and Model of End-Stage Liver Disease used in the AMPEL Project

Calculate observed vs expected mortality

Description

This function creates a table to compare the observed and the expected mortality.

Usage

observed_vs_expected_mortality(x, f, time, expected)

Arguments

x	Surv, object
f	factor, strata/splitting factor
time	numeric(1), observed/expected survival at time timepoint.
expected	numeric, expected mortality rate, has to be of the same length as levels in f.

Value

data.frame, with observed/expected mortality rates and events.

Examples

sv <- Surv(1:8, c(0, 1, 1, 0, 1, 1, 1, 0))
f <- factor(rep(c("a", "c"), 4), levels = c("a", "b", "c"))
observed_vs_expected_mortality(sv, f, time = 3, expected = c(0.5, 0.3, 0.2))
