New Bivariate Wrapped Distributions [PDF]

open access: yesJournal of Mathematics and Statistics, 2016
There are not many models for bivariate directional data. Here, we introduce more than ten new bivariate wrapped distributions. For each distribution, expressions are given for the means, covariances and five correlation coefficients.

Central Regions for Bivariate Distributions

open access: yesAustrian Journal of Statistics, 2016
For a one-dimensional probability distribution, the classical concept of central region as a real interquantile interval arises in all applied sciences. We can find applications, for instance, with dispersion, skewness and detection of outliers.

On Bivariate Nadarajah-Haghighi Distribution derived from Farlie-Gumbel-Morgenstern copula in the Presence of Covariates

open access: yesJournal of Nigerian Society of Physical Sciences, 2023
An important alternative distribution to the Weibull, generalized exponen- tial and gamma distributions that is used in survival analysis is the Nadarajah- Haghighi exponential distribution.

A family of bivariate Pareto distributions

open access: yesStatistica, 2014
Pareto distributions have been extensively used in literature for modelling and analysis of income and lifetime data. In the present paper, we introduce a family of bivariate Pareto distributions using a generalized version of dullness property.

BAMBI: An R Package for Fitting Bivariate Angular Mixture Models

open access: yesJournal of Statistical Software, 2021
Statistical analyses of directional or angular data have applications in a variety of fields, such as geology, meteorology and bioinformatics. There is substantial literature on descriptive and inferential techniques for univariate angular data, with the

Collective estimation of multiple bivariate density functions with application to angular-sampling-based protein loop modeling [PDF]

open access: yes, 2016
This article develops a method for simultaneous estimation of density functions for a collection of populations of protein backbone angle pairs using a data-driven, shared basis that is constructed by bivariate spline functions defined on a triangulation

On bivariate geometric distribution

open access: yesStatistica, 2013
Characterizations of bivariate geometric distribution using univariate and bivariate geometric compounding are obtained. Autoregressive models with marginals as bivariate geometric distribution are developed.

Bivariate and Multivariate Weighted Kumaraswamy Distributions: Theory and Applications

open access: yesJournal of Statistical Theory and Applications (JSTA), 2019
Weighted distributions (univariate and bivariate) have received widespread attention over the last two decades because of their flexibility for analyzing skewed data.

Description of the Joint Probability of Significant Wave Height and Mean Wave Period

open access: yesJournal of Marine Science and Engineering, 2022
The bivariate probability distribution of significant wave heights and mean wave periods has an indispensable guiding role in the implementation of offshore engineering, which has attracted great attention.

Comparisons of Concordance in Additive Models [PDF]

open access: yes, 2012
In this note we compare bivariate additive models with respect to their Pearson correlation coecients, Kendall's concordance coecients, and Blomqvist medial correlation coefcients. The conditions that enable the comparisons involve variability stochastic
