%description
Efficient implementation of Kernel SHAP (Lundberg and Lee, 2017,
<doi:10.48550/arXiv.1705.07874>) permutation SHAP, and additive SHAP for
model interpretability.  For Kernel SHAP and permutation SHAP, if the
number of features is too large for exact calculations, the algorithms
iterate until the SHAP values are sufficiently precise in terms of their
standard errors.  The package integrates smoothly with meta-learning
packages such as 'tidymodels', 'caret' or 'mlr3'. It supports multi-output
models, case weights, and parallel computations.  Visualizations can be
done using the R package 'shapviz'.
