%description
Generalised additive P-spline regression models estimation using the
separation of overlapping precision matrices (SOP) method. Estimation is
based on the equivalence between P-splines and linear mixed models, and
variance/smoothing parameters are estimated based on restricted maximum
likelihood (REML). The package enables users to estimate P-spline models
with overlapping penalties. Based on the work described in
Rodriguez-Alvarez et al. (2015) <doi:10.1007/s11222-014-9464-2>;
Rodriguez-Alvarez et al. (2019) <doi:10.1007/s11222-018-9818-2>, and
