Hierarchical models of rigidity percolation

, 2009
We introduce models of generic rigidity percolation in two dimensions on hierarchical networks, and solve them exactly by means of a renormalization transformation.

Bayesian credibility premium with GB2 copulas

Dependence Modeling, 2020
For observations over a period of time, Bayesian credibility premium may be used to predict the value of a response variable for a subject, given previously observed values.

Empleando modelos jerárquicos para encontrar el mejor modelo para pronosticar los galones de gasolina corriente demandados en Bogotá (Colombia) || Use of hierarchical models to find the best model to forecast the gallons of regular gasoline demanded in Bogotá (Colombia)

Revista de Métodos Cuantitativos para la Economía y la Empresa, 2019
El documento tiene como objetivo encontrar el mejor modelo jerárquico que permita proyectar la demanda total de gasolina corriente y por tanto el recaudo por sobretasa a la gasolina en Bogotá, Colombia, impuesto importante para el financiamiento de la ...

Temporal aggregation of migration counts can improve accuracy and precision of trends

Avian Conservation and Ecology, 2016
Temporal replicate counts are often aggregated to improve model fit by reducing zero-inflation and count variability, and in the case of migration counts collected hourly throughout a migration, allows one to ignore nonindependence. However, aggregation

Count Random Variables

Encyclopedia
The observation of randomness patterns serves as guidance for the craft of probabilistic modelling. The most used count models—Binomial, Poisson, Negative Binomial—are the discrete Morris’ natural exponential families whose variance is at most quadratic ...

Influence of microhabitat on Honduran Emerald (Amazilia luciae) abundance in tropical dry forest remnants

Avian Conservation and Ecology, 2019
Understanding the ecology of at-risk species is the foundation for developing strategies to counteract continued population declines. The Honduran Emerald (Amazilia luciae) is an endemic hummingbird that inhabits tropical dry forest in Honduras ...

Determining dependence among random variables across observations

Ratio Mathematica
It is common in applied research to analyze data from data generating processes with dependencies among random variables across observations.  Such dependencies impact power calculations and standard errors.
