Iterative approximation techniques for B-spline data fitting constitute a family of methods that seek to determine a smooth curve or surface representation of scattered or noisy data by successively ...
The model has a parametric component (associated with the x 1 variable) and a nonparametric component (associated with the x 2 variable). The following statements fit a partial spline model. data ...
