Asymptotic properties of Dirichlet kernel density estimators

F Ouimet, R Tolosana-Delgado - Journal of Multivariate Analysis, 2022 - Elsevier
We study theoretically, for the first time, the Dirichlet kernel estimator introduced by Aitchison
and Lauder (1985) for the estimation of multivariate densities supported on the d …

Large sample results for varying kernel regression estimates

HL Koul, W Song - Journal of Nonparametric Statistics, 2013 - Taylor & Francis
The varying kernel density estimates are particularly designed for positive random variables.
Unlike the commonly used symmetric kernel density estimates, the varying kernel density …

Generalised gamma kernel density estimation for nonnegative data and its bias reduction

G Igarashi, Y Kakizawa - Journal of Nonparametric Statistics, 2018 - Taylor & Francis
We consider density estimation for nonnegative data using generalised gamma density.
What is being emphasised here is that a negative exponent is allowed. We show that, for …

Multivariate elliptical-based Birnbaum–Saunders kernel density estimation for nonnegative data

Y Kakizawa - Journal of Multivariate Analysis, 2022 - Elsevier
Abstract The Birnbaum–Saunders distribution has been generalized in various ways, for
parametric or nonparametric statistical inference. In this paper, as a remedy for the boundary …

Asymptotic properties of asymmetric kernel estimators for non-negative and censored data

S Ghettab, Z Guessoum - Communications in Statistics-Theory and …, 2022 - Taylor & Francis
Let {X i, i≥ 1} be a sequence of independent and identically distributed random variables
with distribution function F and probability density function f. We propose new type of kernel …

Generalised kernel smoothing for non-negative stationary ergodic processes

YP Chaubey, N Laïb, A Sen - Journal of Nonparametric Statistics, 2010 - Taylor & Francis
In this paper, we consider a generalised kernel smoothing estimator of the regression
function with non-negative support, using gamma probability densities as kernels, which are …

Multivariate non-central Birnbaum–Saunders kernel density estimator for nonnegative data

Y Kakizawa - Journal of Statistical Planning and Inference, 2020 - Elsevier
A multivariate Birnbaum–Saunders distribution is introduced to consider a new
nonparametric multivariate density estimation for nonnegative data. By construction, the …

[PDF][PDF] Density estimation using Dirichlet kernels

F Ouimet - arXiv preprint arXiv:2002.06956, 2020 - authors.library.caltech.edu
In this paper, we introduce Dirichlet kernels for the estimation of multivariate densities
supported on the d-dimensional simplex. These kernels generalize the beta kernels from …

Approche non-paramétrique par noyaux associés discrets des données de dénombrement

TS Kiessé - 2008 - theses.hal.science
Nous introduisons une nouvelle approche non-paramétrique, par noyaux associés discrets,
pour les données de dénombrement. Pour cela, nous définissons la notion de noyaux …

An asymmetric kernel estimator of density function for stationary associated sequences

YP Chaubey, I Dewan, J Li - Communications in Statistics …, 2012 - Taylor & Francis
Here, we apply the smoothing technique proposed by Chaubey et al. for the empirical
survival function studied in Bagai and Prakasa Rao for a sequence of stationary non …
