Robust Independent Component Analysis viaMinimum γ-Divergence Estimation [PDF]

open access: yes, 2014
Independent component analysis (ICA) has been shown to be useful in many applications. However, most ICA methods are sensitive to data contamination.

Ensemble estimation of multivariate f-divergence [PDF]

open access: yes2014 IEEE International Symposium on Information Theory, 2014
f-divergence estimation is an important problem in the fields of information theory, machine learning, and statistics. While several divergence estimators exist, relatively few of their convergence rates are known. We derive the MSE convergence rate for a density plug-in estimator of f-divergence.

Parameter Estimation Based on Cumulative Kullback–Leibler Divergence

open access: yesRevstat Statistical Journal, 2021
In this paper, we propose some estimators for the parameters of a statistical model based on Kullback–Leibler divergence of the survival function in continuous setting and apply it to type I censored data.

Multivariate f-Divergence Estimation With Confidence

open access: yesCoRR, 2014
The problem of f-divergence estimation is important in the fields of machine learning, information theory, and statistics. While several nonparametric divergence estimators exist, relatively few have known convergence properties. In particular, even for those estimators whose MSE convergence rates are known, the asymptotic distributions are unknown. We

Strategies for improving approximate Bayesian computation tests for synchronous diversification

open access: yesBMC Evolutionary Biology, 2017
Background Estimating the variability in isolation times across co-distributed taxon pairs that may have experienced the same allopatric isolating mechanism is a core goal of comparative phylogeography.

Estimation of a continuous distribution on the real line by discretization methods [PDF]

open access: yes, 2019
First Online: 24 September 2018For an unknown continuous distribution on the real line, we consider the approximate estimation by discretization. There are two methods for discretization. The first method is to divide the real line into several intervals

Divergence Measures Estimation and Its Asymptotic Normality Theory Using Wavelets Empirical Processes III

open access: yesJournal of Statistical Theory and Applications (JSTA)
In the two previous papers of this series, the main results on the asymptotic behaviors of empirical divergence measures based on wavelets theory have been established and particularized for important families of divergence measures like Rényi and ...

On Inference of Overlapping Coefficients in Two Inverse Lomax Populations

open access: yesJournal of Statistical Theory and Applications (JSTA), 2021
Overlapping coefficient is a direct measure of similarity between two distributions which is recently becoming very useful. This paper investigates estimation for some well-known measures of overlap, namely Matusita's measure ρ, Weitzman's ...

Accounting for calibration uncertainty in phylogenetic estimation of evolutionary divergence times

open access: yes, 2009
The estimation of phylogenetic divergence times from sequence data is an important component of many molecular evolutionary studies. There is now a general appreciation that the procedure of divergence dating is considerably more complex than that ...
