  "Description": "Implements the five-parameter Generalized Kumaraswamy\n('gkw') distribution proposed by 'Carrasco, Ferrari and\nCordeiro (2010)' <doi:10.48550/arXiv.1004.0911> and its seven\nnested sub-families for modeling bounded continuous data on the\nunit interval (0,1). The 'gkw' distribution extends the\nKumaraswamy distribution described by Jones (2009)\n<doi:10.1016/j.stamet.2008.04.001>. Provides density,\ndistribution, quantile, and random generation functions, along\nwith analytical log-likelihood, gradient, and Hessian functions\nimplemented in 'C++' via 'RcppArmadillo' for maximum\ncomputational efficiency. Suitable for modeling proportions,\nrates, percentages, and indices exhibiting complex features\nsuch as asymmetry, or heavy tails and other shapes not\nadequately captured by standard distributions like simple Beta\nor Kumaraswamy.",
