Regression with Ordered Predictors via Ordinal Smoothing Splines

open access: yesFrontiers in Applied Mathematics and Statistics, 2017
Many applied studies collect one or more ordered categorical predictors, which do not fit neatly within classic regression frameworks. In most cases, ordinal predictors are treated as either nominal (unordered) variables or metric (continuous) variables ...

Solving 2D Poisson-type equations using meshless SPH method

open access: yesResults in Physics, 2019
In the present study, 2D Poisson-type equation is solved by a meshless Symmetric Smoothed Particle Hydrodynamics (SSPH) method. The influence of the kernel function, smoothing length and particle discretizations of problem domain on the solutions of ...

Signal Estimation Using Wavelet Analysis of Solution Monitoring Data for Nuclear Safeguards

open access: yesAxioms, 2013
Wavelets are explored as a data smoothing (or de-noising) option for solution monitoring data in nuclear safeguards. In wavelet-smoothed data, the Gibbs phenomenon can obscure important data features that may be of interest.

Nonparametric Kernel Smoothing Methods. The sm library in Xlisp-Stat

open access: yesJournal of Statistical Software, 2001
In this paper we describe the Xlisp-Stat version of the sm library, a software for applying nonparametric kernel smoothing methods. The original version of the sm library was written by Bowman and Azzalini in S-Plus, and it is documented in their book ...

A Note on Nonparametric Estimation of Conditional Hazard Quantile Function [PDF]

open access: yesJournal of Risk Analysis and Crisis Response (JRACR), 2017
In this paper, we study an kernel estimator of the conditional hazard quantile function (CHQF) of a scalar response variable Y given a random variable (rv) X taking values in a semi-metric space and using the proposed estimator based of the kernel ...

Optimum kernels

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2004
Kernel smoothers belong to the most popular nonparametric functional estimates. They provide a simple way of finding structure in data. Kernel smoothing can be very well applied on the regression model.
