Application of the Scaling Functions to Nonparametric Regression [PDF]

open access: yesInformatică economică, 2007
For estimating regression function we can use many proceedings. In this paper, we have chosen to apply scaling functions to the estimation of regression functions.

Estimating Cumulative Distribution Function Using Gamma Kernel [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2022
In this article, we propose the gamma kernel estimator for the cumulative distribution functions with nonnegative support. We derive the asymptotic bias and variance of the proposed estimator in both boundary and interior regions and show that it is free

Variational Estimation Methods for Sturm–Liouville Problems

open access: yesMathematics, 2022
In this paper, we are concerned with approach solutions for Sturm–Liouville problems (SLP) using variational problem (VP) formulation of regular SLP.

Parameter estimation methods for random point fields with local interactions [PDF]

open access: yesКомпьютерные исследования и моделирование, 2016
The paper gives an overview of methods for estimating the parameters of random point fields with local interaction between points. It is shown that the conventional method of the maximum pseudo-likelihood is a special case of the family of estimation ...

Estimating a Distribution Function at the Boundary

open access: yesAustrian Journal of Statistics, 2020
Estimation of distribution functions has many real-world applications. We study kernel estimation of a distribution function when the density function has compact support. We show that, for densities taking value zero at the endpoints of the support, the

Spline estimator and its asymptotic properties in multiresponse nonparametric regression model [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
In applications, we often meet the problem where more than one response variable is observed at several values of predictor variables, and these responses are correlated with each other.

Quasi-likelihood for Spatial Point Processes [PDF]

open access: yes, 2013
Fitting regression models for intensity functions of spatial point processes is of great interest in ecological and epidemiological studies of association between spatially referenced events and geographical or environmental covariates.

A Utility Based Approach to Energy Hedging [PDF]

open access: yes, 2011
A key issue in the estimation of energy hedges is the hedgers' attitude towards risk which is encapsulated in the form of the hedgers' utility function.

Optimal variance estimation without estimating the mean function [PDF]

open access: yes, 2013
We study the least squares estimator in the residual variance estimation context. We show that the mean squared differences of paired observations are asymptotically normally distributed.

Model choice for estimating the association between exposure to chemical mixtures and health outcomes: A simulation study.

open access: yesPLoS ONE, 2021
Challenges arise in researching health effects associated with chemical mixtures. Several methods have recently been proposed for estimating the association between health outcomes and exposure to chemical mixtures, but a formal simulation study ...
