%description
Provides probability density functions and sampling algorithms for three
key distributions from the General Unimodal Distribution (GUD) family: the
Flexible Gumbel (FG) distribution, the Double Two-Piece (DTP) Student-t
distribution, and the Two-Piece Scale (TPSC) Student-t distribution.
Additionally, this package includes a function for Bayesian linear modal
regression, leveraging these three distributions for model fitting. The
details of the Bayesian modal regression model based on the GUD family can
be found at Liu, Huang, and Bai (2024) <doi:10.1016/j.csda.2024.108012>.
