Nonparametric Pointwise Estimation for a Regression Model with Multiplicative Noise

open access: yesJournal of Function Spaces, 2021
In this paper, we consider a general nonparametric regression estimation model with the feature of having multiplicative noise. We propose a linear estimator and nonlinear estimator by wavelet method.

A Nonparametric Estimator of Species Overlap [PDF]

open access: yesBiometrics, 2001
For two communities, species overlap has been defined by Smith, Solow, and Preston (1996, Biometrics 52, 1472-1477) as the probability that a randomly selected species is present in both communities given that it is present in at least one community. Species overlap can thus be used to describe the similarity of two communities.

A Bayesian nonparametric estimation to entropy [PDF]

open access: yesBrazilian Journal of Probability and Statistics, 2021
A Bayesian nonparametric estimator to entropy is proposed. The derivation of the new estimator relies on using the Dirichlet process and adapting the well-known frequentist estimators of Vasicek (1976) and Ebrahimi, Pflughoeft and Soofi (1994). Several theoretical properties, such as consistency, of the proposed estimator are obtained.

Nonparametric Mean Estimation for Big-but-Biased Data

open access: yesProceedings, 2018
Some authors have recently warned about the risks of the sentence with enough data, the numbers speak for themselves. The problem of nonparametric statistical inference in big data under the presence of sampling bias is considered in this work.

High throughput nonparametric probability density estimation. [PDF]

open access: yesPLoS ONE, 2018
In high throughput applications, such as those found in bioinformatics and finance, it is important to determine accurate probability distribution functions despite only minimal information about data characteristics, and without using human subjectivity.

Bayesian nonparametric subspace estimation [PDF]

open access: yes2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017
Principal component analysis is a widely used technique to perform dimension reduction. However, selecting a finite number of significant components is essential and remains a crucial issue. Only few attempts have proposed a probabilistic approach to adaptively select this number. This paper introduces a Bayesian nonparametric model to jointly estimate

Pointwise Estimation of Anisotropic Regression Functions Using Wavelets with Data-Driven Selection Rule

open access: yesMathematics, 2023
For nonparametric regression estimation, conventional research all focus on isotropic regression function. In this paper, a linear wavelet estimator of anisotropic regression function is constructed, the rate of convergence of this estimator is discussed
