%description
Implements Heckman selection models using a Bayesian approach via 'Stan'
and compares the performance of normal, Student’s t, and contaminated
normal distributions in addressing complexities and selection bias (Heeju
Lim, Victor E. Lachos, and Victor H. Lachos, Bayesian analysis of flexible
Heckman selection models using Hamiltonian Monte Carlo, 2025, under
submission).
