  "Description": "Fits and analyzes simplex regression models with either\nfixed or parametric mean link functions. Implements the simplex\nprobability density function, cumulative distribution function,\nquantile function, random number generation, and variance\nevaluation. Offers several fixed and parametric link functions\nfor the mean submodel, tools for residual analysis and\ndiagnostic plotting, hypothesis testing procedures, and\ninfluence measures such as Cook's distance and leverage (hat\nvalues). Includes the Scout Score (SS) criterion for model\nselection, enabling comprehensive inference and diagnostic\nanalysis within the simplex regression framework. For more\ndetails see Barndorff-Nielsen and Jorgensen (1991)\n<doi:10.1016/0047-259X(91)90008-P> and Justino and Cribari-Neto\n(2026) <doi:10.1016/j.apm.2025.116713>.",
