Covariance Structure Modeling of Engineering Demand Parameters in Cloud‐Based Seismic Analysis
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1533-1551, June 2026.ABSTRACT Probabilistic seismic demand modeling aims to estimate structural demand as a function of ground motion intensity—a critical stage in seismic risk assessment. Although many models exist to describe the structural demand, few consider the covariance among engineering demand parameters, potentially overlooking a key factor in improving the ...

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions
Earth and Space Science, Volume 13, Issue 6, June 2026.Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.

"On a limiting quasi-multinomial distribution" [PDF]
A random clustering distribution is useful for modeling count data. The present article derives a new distribution of this type from the Lagrangian Poisson distribution, based on the result that any infinitely divisible distribution over nonnegative ...

Correlation in Bivariate Poisson Regression Model [PDF]
, 2007 We consider a bivariate Poisson model that is based on the lognormal heterogeneity model. Two recent applications have used this model. We suggest that the correlation estimated in their model frameworks is an ambiguous measure of the correlation of the ...

Simultaneously Modelling Occurrence and Quantity of Multivariate Semicontinuous Data
Australian &New Zealand Journal of Statistics, Volume 68, Issue 2, June 2026.ABSTRACT Joint models have been developed recently for multivariate semicontinuous data; however, joint modelling implies structured covariance and nonnegative correlation among responses, and thus is inflexible in accommodating complex covariance structures in practice.

, 2021 Actuary in the insurance company should have expertise in measuring and controlling risks of the aggregate claims. The risk of a claim generally measured using the variance, but often can’t accommodate all the events of claim risks.

Brazilian Journal of Biology, 2010 In this paper we examine the accuracy and precision of three indices of catch-per-unit-effort (CPUE). We carried out simulations, generating catch data according to six probability distributions (normal, Poisson, lognormal, gamma, delta and negative ...

Journal of Biogeography, Volume 53, Issue 6, June 2026.ABSTRACT Aim Quaternary climatic oscillations have profoundly shaped the genetic structure and geographic distributions of alpine biotas. Understanding how cold‐adapted taxa responded to past climatic shifts is essential for unravelling the processes shaping mountain biodiversity, yet cold‐adapted taxa may have followed divergent refugial histories. We
