A MATLAB Package for Markov Chain Monte Carlo with a Multi-Unidimensional IRT Model [PDF]
Unidimensional item response theory (IRT) models are useful when each item is designed to measure some facet of a unified latent trait. In practical applications, items are not necessarily measuring the same underlying trait, and hence the more general ...

Contributions to Plasma Physics, EarlyView.ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

IMPOSING CURVATURE RESTRICTIONS ON A TRANSLOG COST FUNCTION USING A MARKOV CHAIN MONTE CARLO SIMULATION APPROACH [PDF]
Using Kansas Farm data from 1973 to 1998, curvature restrictions are imposed on a translog cost function. Using uninformative priors with indicator functions representing distribution and inequality constraints, a Markov Chain Monte Carlo Simulation ...

Microclimate mediates the strength and direction of avian biotic interactions
Ecography, EarlyView.Theory predicts that the strength and direction of species interactions can shift from being competitive in benign environments toward being facilitative in stressful environments. However, the environmental context dependency of species interactions has rarely been tested in animal communities.

Convergence of Markov chain approximations to stochastic reaction diffusion equations.
, 2002 In the context of simulating the transport of a chemical or bacterial contaminant through a moving sheet of water, we extend a well-established method of approximating reaction-diffusion equations with Markov chains by allowing convection, certain ...

Ecography, EarlyView.Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Ecography, EarlyView.The core of Janzen's tropical mountain passes hypothesis is that relatively stable annual temperature variation limits species' thermal tolerances breadth, which, in combination with steep elevational temperature gradients, constrains the elevational distributions of these species. In addition to thermal niche breadth, elevational ranges were shaped by
