%description
Provides a full pipeline from regularized or standard regression models
(elastic net, linear models, generalized linear models, random forests) to
informed Bayesian priors, structured forecast uncertainty decomposition
(parameter / environmental / residual, plus a temporal component when the
model carries an autocorrelation term), and forecast shelf life analysis
(the quantification of when a forecast becomes uninformative). Designed
for ecological and genomic forecasting with climate or environmental
covariates. Methods build on Bürkner (2017) <doi:10.18637/jss.v080.i01>
for Bayesian regression via 'Stan', Friedman, Hastie, and Tibshirani
(2010) <doi:10.18637/jss.v033.i01> for elastic net regularization, Wright
and Ziegler (2017) <doi:10.18637/jss.v077.i01> for random forests, and
Vehtari, Gelman, and Gabry (2017) <doi:10.1007/s11222-016-9696-4> for
leave-one-out cross-validation.
