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

#' @keywords internal
#' @aliases BetaDanish-package
#' 
#' @details 
#' The `BetaDanish` package provides a comprehensive suite of tools for survival 
#' and reliability analysis using the Beta-Danish distribution. It includes core 
#' mathematical functions (density, distribution, quantile, random generation, 
#' and hazard), robust Maximum Likelihood Estimation (MLE) for both complete and 
#' right-censored data, and advanced modeling capabilities including Accelerated 
#' Failure Time (AFT) regression, cure-rate models, and competing risks analysis.
