fit_bd_competing: Fit Beta-Danish Competing Risks Model

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

Fit Beta-Danish Competing Risks Model

Description

Fits a parametric competing risks model assuming independent latent failure times, where each cause-specific baseline follows a 4-parameter Beta-Danish distribution.

Usage

fit_bd_competing(time, cause, n_starts = 5, method = "BFGS")

Arguments

time	Numeric vector of observed times.
cause	Integer vector of event causes. '0' indicates right-censored, and '1, 2, ..., m' indicate specific event causes.
n_starts	Integer; number of random starts for the joint optimization.
method	Optimization method passed to 'maxLik'.

Details

Under the assumption of independent latent failure times, the joint likelihood factorizes. The function first fits independent Beta-Danish models for each cause (treating other causes as censored) to find robust starting values, then optimizes the joint likelihood.

Value

An object of class 'bd_competing'.
