%description
Implements Bayesian Lasso regression using efficient Gibbs sampling
algorithms, including modified versions of the Hans and Park–Casella (PC)
samplers. Includes functions for working with the Lasso distribution, such
as its density, cumulative distribution, quantile, and random generation
functions, along with moment calculations. Also includes a function to
compute the Mills ratio. Designed for sparse linear models and suitable
for high-dimensional regression problems.
