Nonparametric Estimation from Incomplete Observations

open access: yes, 1958
In lifetesting, medical follow-up, and other fields the observation of the time of occurrence of the event of interest (called a death) may be prevented for some of the items of the sample by the previous occurrence of some other event (called a loss ...

Nonparametric Information Geometry [PDF]

open access: yes, 2013
The differential-geometric structure of the set of positive densities on a given measure space has raised the interest of many mathematicians after the discovery by C.R. Rao of the geometric meaning of the Fisher information.

kdecopula: An R Package for the Kernel Estimation of Bivariate Copula Densities

open access: yesJournal of Statistical Software, 2018
We describe the R package kdecopula (current version 0.9.2), which provides fast implementations of various kernel estimators for the copula density. Due to a variety of available plotting options it is particularly useful for the exploratory analysis of

Online nonparametric Bayesian analysis of parsimonious Gaussian mixture models and scenes clustering

open access: yesETRI Journal, 2020
The mixture model is a very powerful and flexible tool in clustering analysis. Based on the Dirichlet process and parsimonious Gaussian distribution, we propose a new nonparametric mixture framework for solving challenging clustering problems. Meanwhile,

Heterogeneity and the nonparametric analysis of consumer choice: conditions for invertibility [PDF]

open access: yes, 2005
This paper considers structural nonparametric random utility models for continuous choice variables. It provides sufficient conditions on random preferences to yield reduced- form systems of nonparametric stochastic demand functions that allow global ...

Nonparametric and Semi‐Nonparametric Recreational Demand Analysis [PDF]

open access: yesAmerican Journal of Agricultural Economics, 2000
AbstractThis paper addresses issues of specification testing for the travel cost method (TCM). Two nonparametric approaches to TCM analysis are presented. In addition, semi‐nonparametric count models for TCM are developed. A numerical illustration is provided in which the three methods are applied to an actual TCM data set on waterfowl hunting and the ...

Spatially Dependent Bayesian Modeling of Geostatistics Data and Its Application for Tuberculosis (TB) in China

open access: yesMathematics, 2023
Geostatistics data in regions always have highly spatial heterogeneous, yet the regional features of the data itself cannot be ignored. In this paper, a novel latent Bayesian spatial model is proposed, which incorporates the spatial dependence of ...

An Information-Based Approach for Mediation Analysis on High-Dimensional Metagenomic Data

open access: yesFrontiers in Genetics, 2020
The human microbiome plays a critical role in the development of gut-related illnesses such as inflammatory bowel disease and clinical pouchitis. A mediation model can be used to describe the interaction between host gene expression, the gut microbiome ...
