-Description: Routines to construct general P-splines for non-uniform B-splines on arbitrary knots, proposed by Li and Cao (2022) <arXiv:2201.06808>. This P-spline variant extends the standard P-splines of Eilers and Marx (1996) <doi:10.1214/ss/1038425655> that are tailored for uniform B-splines on equidistant knots. Includes SparseD() for computing general difference matrices, SparseS() for computing derivative penalty matrix or its sparse root using a sandwich formula, etc. Also includes several demos on B-splines and P-splines. Aims to facilitate other packages to implement general P-splines as a smoothing tool in their model estimation framework.
+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.
