 Description: Efficient approximate leave-one-out cross-validation (LOO)
-    for Bayesian models fit using Markov chain Monte Carlo, as 
-    described in Vehtari, Gelman, and Gabry (2017) 
-    <doi:10.1007/s11222-016-9696-4>. 
-    The approximation uses Pareto smoothed importance sampling (PSIS), 
-    a new procedure for regularizing importance weights. 
-    As a byproduct of the calculations, we also obtain approximate 
-    standard errors for estimated predictive errors and for the comparison 
-    of predictive errors between models. The package also provides methods 
-    for using stacking and other model weighting techniques to average 
-    Bayesian predictive distributions.
