Computationally Efficient Bootstrap Expressions for Bandwidth Selection in Nonparametric Curve Estimation

open access: yesProceedings, 2018
Bootstrap methods are used for bandwidth selection in: (1) nonparametric kernel density estimation with dependent data (smoothed stationary bootstrap and smoothed moving blocks bootstrap), and (2) nonparametric kernel hazard rate estimation (smoothed ...

Smooth Dependence of Topological Conjugacies on Parameters

open access: yesAdvanced Nonlinear Studies, 2011
Abstract For nonautonomous linear equations xʹ = A(t)x with a nonuniform exponential dichotomy, we show that under sufficiently small C 1 parameter-dependent perturbations, namely of the form xʹ = A(t)x + f (t, x, λ), the topological conjugacies in an appropriate version of ...

A Novel Dynamic Absorber with Variable Frequency and Damping

open access: yesShock and Vibration, 2021
Smoothness and discontinuous (SD) oscillator is a nonlinear oscillator with the variable frequency, whose frequency can be varied with the smoothing parameter. However, how to adjust the smoothing parameter has not been solved in the actual device.

Smoothing of, and parameter estimation from, noisy biophysical recordings. [PDF]

open access: yesPLoS Computational Biology, 2009
Biophysically detailed models of single cells are difficult to fit to real data. Recent advances in imaging techniques allow simultaneous access to various intracellular variables, and these data can be used to significantly facilitate the modelling task.

Efficient algorithms for robust generalized cross-validation spline smoothing

open access: yes, 2010
Generalized cross-validation (GCV) is a widely used parameter selection criterion for spline smoothing, but it can give poor results if the sample size n is not sufficiently large.

Automatic Smoothing Parameter Selection: A Survey [PDF]

open access: yesEmpirical Economics, 1988
This is a survey of recent developments in smoothing parameter selection for curve estimation. The first goal of this paper is to provide an introduction to the methods available, with discussion at both a practical and also a nontechnical level, including comparison of methods.
