Why Are FGM Copulas Successful? A Simple Explanation
One of the most computationally convenient nonredundant ways to describe the dependence between two variables is by describing the corresponding copula.

Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

A Note on Identification of Bivariate Copulas for Discrete Count Data
Copulas have enjoyed increased usage in many areas of econometrics, including applications with discrete outcomes. However, Genest and Neslehova (2007) present evidence that copulas for discrete outcomes are not identified, particularly when those ...

Using expert elicitation to predict feral cat, Felis catus, responses to management
We generated estimates of lethal feral cat management success for 864 scenarios, only 71 lethal management scenarios met a population reduction target of 57%. Cat‐targeted poison baits, in dry conditions and arid areas were most successful. Feral cat management requires continued adaptive strategies to reduce cat impacts.

New copulas based on general partitions-of-unity and their applications to risk management
We construct new multivariate copulas on the basis of a generalized infinite partition-of-unity approach. This approach allows, in contrast to finite partition-of-unity copulas, for tail-dependence as well as for asymmetry.

An objective Bayesian method for including parameter uncertainty in ensemble model output statistics
Conventional model output statistics and ensemble model output statistics methods for calibrating ensemble forecasts lead to severe underestimation of the probabilities of ensemble extremes (in blue). This is because they ignore statistical parameter uncertainty.

Bounds for Trivariate Copulas with Given Bivariate Marginals
We determine two constructions that, starting with two bivariate copulas, give rise to new bivariate and trivariate copulas, respectively. These constructions are used to determine pointwise upper and lower bounds for the class of all trivariate copulas ...

The dual graph neural network (dualGNN), trained with a composite loss combining the energy score (ES) and variogram score (VS), consistently outperformed models optimized solely for ES or the continuous ranked probability score in the multivariate setting, as well as empirical copula approaches.
