%description
General P-splines are non-uniform B-splines penalized by a general
difference penalty, proposed by Li and Cao (2022) <arXiv:2201.06808>.
Constructible on arbitrary knots, they extend the standard P-splines of
Eilers and Marx (1996) <doi:10.1214/ss/1038425655>. They are also related
to the O-splines of O'Sullivan (1986) <doi:10.1214/ss/1177013525> via a
sandwich formula that links a general difference penalty to a derivative
penalty. The package includes routines for setting up and handling
difference and derivative penalties. It also fits P-splines and O-splines
to (x, y) data (optionally weighted) for a grid of smoothing parameter
values in the automatic search intervals of Li and Cao (2023)
<doi:10.1007/s11222-022-10178-z>. It aims to facilitate other packages to
implement P-splines or O-splines as a smoothing tool in their model
estimation framework.
