%description
Kernel regularized least squares, also known as kernel ridge regression,
is a flexible machine learning method. This package implements this method
by providing a smooth term for use with 'mgcv' and uses random sketching
to facilitate scalable estimation on large datasets. It provides
additional functions for calculating marginal effects after estimation and
for use with ensembles ('SuperLearning'), double/debiased machine learning
('DoubleML'), and robust/clustered standard errors ('sandwich'). Chang and
Goplerud (2023) <arXiv:2209.14355> provide further details.
