Web8 de dez. de 2008 · Now we have shown that our prior distribution on θ c can be translated into a penalty matrix for spline coefficients α c in a penalized spline problem. Given values of η and γ and using the penalty matrix in equation (9) , we can calculate the penalized spline coefficient estimates as α ^ c = D η , γ U ′ U D η , γ U ′ + Σ ^ c − 1 θ ^ c and the … Web19 de mar. de 2024 · Download PDF Abstract: We consider two-stage scattered data fitting with truncated hierarchical B-splines (THB-splines) for the adaptive reconstruction of industrial models. The first stage of the scheme is devoted to the computation of local least squares variational spline approximations, exploiting a simple fairness functional to …
