simulate_bd_cure_data: Simulate Beta-Danish Cure Data

In BetaDanish: The Beta-Danish Distribution for Lifetime Data Analysis

Simulate Beta-Danish Cure Data

Description

Generates synthetic survival data from a Beta-Danish mixture or promotion-time cure model, incorporating covariates.

Usage

simulate_bd_cure_data(
  n,
  type = c("mixture", "promotion"),
  a = 1,
  b = 2,
  c = 1.5,
  delta,
  gamma,
  X,
  Z,
  target_censor = 0.3,
  seed = NULL
)

Arguments

n	Integer; number of observations.
type	Character; '"mixture"' or '"promotion"'.
a, b, c	Numeric; baseline shape parameters.
delta	Numeric vector; coefficients for the latency scale 'k'.
gamma	Numeric vector; coefficients for the incidence/cure component.
X	Matrix; design matrix for latency (must match length of 'delta').
Z	Matrix; design matrix for incidence (must match length of 'gamma').
target_censor	Numeric; target proportion of censoring to calibrate the exponential censoring rate. Default is 0.3.
seed	Integer; optional seed.

Value

A list containing the simulated 'data' (time, status), the 'cured' indicator, and the true parameters.
