%description
Implements Self-Validated Ensemble Models (SVEM, Lemkus et al. (2021)
<doi:10.1016/j.chemolab.2021.104439>) using Elastic Net regression via
'glmnet' (Friedman et al. <doi:10.18637/jss.v033.i01>). SVEM averages
predictions from multiple models fitted to fractionally weighted
bootstraps of the data, tuned with anti-correlated validation weights.
Also implements the randomized permutation whole model test for SVEM (Karl
(2024) <doi:10.1016/j.chemolab.2024.105122>). \Code for the whole model
test was taken from the supplementary material of Karl (2024). Development
of this package was assisted by 'GPT o1-preview' for code structure and
documentation.
