%description
Cross-validation methods of regression models that exploit features of
various modeling functions to improve speed. Some of the methods
implemented in the package are novel, as described in the package
vignettes; for general introductions to cross-validation, see, for
example, Gareth James, Daniela Witten, Trevor Hastie, and Robert
Tibshirani (2021, ISBN 978-1-0716-1417-4, Secs. 5.1, 5.3), "An
Introduction to Statistical Learning with Applications in R, Second
Edition", and Trevor Hastie, Robert Tibshirani, and Jerome Friedman (2009,
ISBN 978-0-387-84857-0, Sec. 7.10), "The Elements of Statistical Learning,
Second Edition".
