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

Double Kernel Method Using Line Transect Sampling

open access: yesAustrian Journal of Statistics, 2016
A double kernel method as an alternative to the classical kernel method is proposed to estimate the population abundance by using line transect sampling.

Estimation of average treatment effect based on a multi-index propensity score

open access: yesBMC Medical Research Methodology, 2022
Background Estimating the average effect of a treatment, exposure, or intervention on health outcomes is a primary aim of many medical studies. However, unbalanced covariates between groups can lead to confounding bias when using observational data to ...

Nonparametric estimate remarks

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2006
Kernel smoothers belong to the most popular nonparametric functional estimates. They provide a simple way of finding structure in data. The idea of the kernel smoothing can be applied to a simple fixed design regression model.

Smooth Kernel Estimation of a Circular Density Function: A Connection to Orthogonal Polynomials on the Unit Circle

open access: yesJournal of Probability and Statistics, 2018
The circular kernel density estimator, with the wrapped Cauchy kernel, is derived from the empirical version of Carathéodory function that is used in the literature on orthogonal polynomials on the unit circle.

Double Kernel Estimation of Sensitivities [PDF]

open access: yesJournal of Applied Probability, 2009
In this paper we address the general issue of estimating the sensitivity of the expectation of a random variable with respect to a parameter characterizing its evolution. In finance, for example, the sensitivities of the price of a contingent claim are called the Greeks. A new way of estimating the Greeks has recently been introduced in Elie, Fermanian

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 ...

A Berry-Esseen Type Bound in Kernel Density Estimation for Negatively Associated Censored Data

open access: yesJournal of Applied Mathematics, 2013
We discuss the kernel estimation of a density function based on censored data when the survival and the censoring times form the stationary negatively associated (NA) sequences.

Henderson's method approach to Kernel prediction in partially linear mixed models

open access: yesCumhuriyet Science Journal, 2020
In this article, we propose Kernel prediction in partially linear mixed models by using Henderson's method approach. We derive the Kernel estimator and the Kernel predictor via the mixed model equations (MMEs) of Henderson's that they give the best ...

Asymptotic Behaviors of Nearest Neighbor Kernel Density Estimator in Left-truncated Data [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2014
Kernel density estimators are the basic tools for density estimation in non-parametric statistics.  The k-nearest neighbor kernel estimators represent a special form of kernel density estimators, in  which  the  bandwidth  is varied depending on the ...
