Nonparametric Density Estimation in a Mixed Model Using Wavelets

open access: yesAxioms
This paper investigates nonparametric estimations of a density function within a mixed density model. A linear wavelet density estimator and an adaptive nonlinear wavelet estimator are proposed using wavelet method and hard thresholding algorithm.

Nonparametric density estimation of continuous part of a mixed measure

open access: yesStatistica, 2007
We consider a pair of random variables(X,Y) whose probability measure is the sum of an absolutely continuous measure, a discrete measure and a finite number of absolutely continuous measures on several lines(1).

Nonparametric Method for Modeling Clustering Phenomena in Emergency Calls Under Spatial-Temporal Self-Exciting Point Processes

open access: yesIEEE Access, 2019
In this paper, a nonparametric spatial-temporal self-exciting point process is proposed to model clustering features in emergency calls. Gaussian kernel density functions are considered.

Nonparametric density estimation using a multidimensional mixture model of Gaussian distributions

open access: yesLietuvos Matematikos Rinkinys, 2005
This paper algorithmically and empirically studies five major types of nonparametric multivariate density estimation techniques, where no assumption is made about data being drawn from any of known parametric families of distribution. There is developed

Empirical Density Estimation for Interval Censored Data

open access: yesAustrian Journal of Statistics, 2016
This paper is concerned with the nonparametric estimation of a density function when the data are incomplete due to interval censoring. The Nadaraya-Watson kernel density estimator is modified to allow description of such interval data.

Nonparametric Bayesian inference for multidimensional compound Poisson processes

open access: yesModern Stochastics: Theory and Applications, 2015
Given a sample from a discretely observed multidimensional compound Poisson process, we study the problem of nonparametric estimation of its jump size density $r_{0}$ and intensity $\lambda _{0}$.

The benchden Package: Benchmark Densities for Nonparametric Density Estimation

open access: yesJournal of Statistical Software, 2012
This article describes the benchden package which implements a set of 28 example densities for nonparametric density estimation in R. In addition to the usual functions that evaluate the density, distribution and quantile functions or generate random ...
