Additive modelling offers a flexible framework in which a response variable is expressed as the sum of smooth functions of predictors. Central to this approach are smoothing techniques that control ...
where belongs to the set of all continuously differentiable functions with square integrable second derivatives, and is a positive constant. Note The computations for a thin-plate smoothing spline are ...
The TSPLINE subroutine computes thin-plate smoothing spline (TPSS) fits to approximate smooth multivariate functions that are observed with noise. The generalized cross validation (GCV) function is ...
