Bayesian Lasso. It does demonstrate Bayesian Lassos potential and the flexibility of greta in probabilistic modeling. The Bayesian lasso model and Gibbs Sampling algorithm is described in detail in Park.

Bayesian LASSO also tends to distribute an effect among collinear variables making detection of an association difficult.
We propose to solve this problem by considering not only individual effects but also their functionals ie. Is another parameter which the authors suggest giving an. Constraints are imposed through prior distributions. The paths are smooth like ridge regression but are more simi-lar in shape to the Lasso paths particularly when the L1 norm is relatively small.
