چکیده
With the aim of generalizing P-splines, we here define a special type penalized splines, called HP-splines, where polynomial splines are replaced by richer class hyperbolic-polynomial and suitably tailored discrete penalty term is used. Hyperbolic-polynomial important in several applications, natural generalization consisting piecewise-defined functions with segments spanned ‘atoms’ x r e ? = 0 , … ? ? R . that reduce to P-splines for more suitable data an exponential trend which frequent applications.

Constrained Penalized Splines
The penalized spline is a popular method for function estimation when the assumption of “smoothness” is valid. In this paper, methods for estimation and inference are proposed using penalized splines under the additional constraints of shape, such as monotonicity or convexity. The constrained penalized spline estimator is shown to have the same convergence rates as the corresponding unconstrain...
متن کاملFast Adaptive Penalized Splines
This paper proposes a numerically simple routine for locally adaptive smoothing. The locally heterogeneous regression function is modelled as a penalized spline with a smoothly varying smoothing parameter modelled as another penalized spline. This is being formulated as hierarchical mixed model, with spline coefficients following a normal distribution, which by itself has a smooth structure ove...
متن کاملBivariate Penalized Splines for Regression
In this paper the asymptotic behavior of penalized spline estimators is studied using bivariate splines over triangulations and an energy functional as the penalty. The rate of L2 convergence is derived, which achieves the optimal nonparametric convergence rate established by Stone (1982). The asymptotic normality of the penalized spline estimators is established, which is shown to hold uniform...
متن کاملSpatially Adaptive Bayesian Penalized Regression Splines (P-splines)
In this paper we study penalized regression splines (P-splines), which are low–order basis splines with a penalty to avoid undersmoothing. Such P–splines are typically not spatially adaptive, and hence can have trouble when functions are varying rapidly. Our approach is to model the penalty parameter inherent in the P–spline method as a heteroscedastic regression function. We develop a full Bay...
متن کاملVariable degree polynomial splines are Chebyshev splines
Variable degree polynomial (VDP) splines have recently proved themselves as a valuable tool in obtaining shape preserving approximations. However, some usual properties which one would expect of a spline space in order to be useful in geometric modeling, do not follow easily from their definition. This includes total positivity (TP) and variation diminishing, but also constructive algorithms ba...
