Correlation of hard X-ray and type 3 bursts in solar flares [PDF]

Correlations between X-ray and type 3 radio emission of solar bursts are described through a bivariate distribution function. Procedures for determining the form of this distribution are described.

Bayesian and Non-Bayesian Inference to Bivariate Alpha Power Burr-XII Distribution with Engineering Application

Axioms
In this research, we present a new distribution, which is the bivariate alpha power Burr-XII distribution, based on the alpha power Burr-XII distribution. We thoroughly examine the key features of our newly developed bivariate model.

A Bivariate Weibull Distribution and its Applications in Reliability

Revstat Statistical Journal
In this article, the bivariate exponential distribution proposed by Downton (“Bivariate exponential distributions in reliability theory”, Journal of the Royal Statistical Society Series B, 1970) is extended to a bivariate Weibull distribution, and it is

A Bivariate Extension of Type-II Generalized Crack Distribution for Modeling Heavy-Tailed Losses

Mathematics
As an extension of the (univariate) Birnbaum–Saunders distribution, the Type-II generalized crack (GCR2) distribution, built on an appropriate base density, provides a sufficient level of flexibility to fit various distributional shapes, including heavy ...

Bivariate Simplex Distribution

This article proposes a bivariate Simplex distribution for modeling continuous outcomes constrained to the interval $(0,1)$, which can represent proportions, rates, or indices. We derive analytical expressions to calculate the dependence between the variables and examine its relationship with the association parameter.

Absolutely Continuous Bivariate Modified Weibull Distribution: Properties and Estimation

Journal of Statistical Theory and Applications (JSTA)
A Block-Basu bivariate exponential (BBBE) distribution is one of the most popular and widely used absolutely continuous bivariate distributions. Later, Kundu and Gupta (Stat Method 7:464–477, 2010) obtained the Block-Basu bivariate Weibull (BBBW ...
