%description
Implements the five-parameter Generalized Kumaraswamy ('gkw') distribution
proposed by 'Carrasco, Ferrari and Cordeiro (2010)'
<doi:10.48550/arXiv.1004.0911> and its seven nested sub-families for
modeling bounded continuous data on the unit interval (0,1). The 'gkw'
distribution extends the Kumaraswamy distribution described by Jones
(2009) <doi:10.1016/j.stamet.2008.04.001>. Provides density, distribution,
quantile, and random generation functions, along with analytical
log-likelihood, gradient, and Hessian functions implemented in 'C++' via
'RcppArmadillo' for maximum computational efficiency. Suitable for
modeling proportions, rates, percentages, and indices exhibiting complex
features such as asymmetry, or heavy tails and other shapes not adequately
captured by standard distributions like simple Beta or Kumaraswamy.
