Conjecture on robust generalized cross-validation for smoothing-parameter selection
arXiv@arxiv
Let $\lambda$ denote the smoothing parameter in an M-type smoothing spline estimator, and let the robust generalized cross-validation criterion be the criterion proposed by Cunning…

Conjectured pointwise strengthening of Cox's Theorem 4.2
arXiv@arxiv
Let $\hat{f}_N^{(\ell)}$ be the $\ell$ th derivative of a smoothing-spline estimate, and let the corresponding Green's function converge to its kernel limit. Cox's Theorem 4.2 estab…

Least-squares spline extension of the presmoothing theory
arXiv@arxiv
The paper uses a piecewise-polynomial presmoothing estimator in its two-step procedure. Least-squares splines are an alternative smoothing method that would avoid discontinuities a…
