Log-rank test — Survival-class • adoptr

Implements the normal approximation of the log-rank test statistic.

Usage

Survival(event_rate, two_armed = TRUE)

# S4 method for class 'Survival'
quantile(x, probs, n, theta, ...)

# S4 method for class 'Survival,numeric'
simulate(object, nsim, n, theta, seed = NULL, ...)

Arguments

event_rate: probability that a subject will eventually have an event
two_armed: logical indicating if a two-armed trial is regarded
x: outcome
probs: vector of probabilities
n: sample size
theta: distribution parameter
...: further optional arguments
object: object of class Survival
nsim: number of simulation runs
seed: random seed

Slots

event_rate: cf. parameter 'event_rate'
