2006 journal article

Sensitivity of ecological models to their climate drivers: Statistical ensembles for forcing

ECOLOGICAL APPLICATIONS, 16(1), 99–116.

By: M. Fuentes n, T. Kittel* & D. Nychka*

author keywords: Bayesian inference; ecological numerical models; kriging; nonstationary process; spatial statistics; variogram
MeSH headings : Animals; Climate; Computer Simulation; Ecology; Ecosystem; Humans; Models, Biological; Models, Theoretical; Population Density; Sensitivity and Specificity; Time Factors; Uncertainty; United States
TL;DR: This work introduces a Bayesian statistical framework to model climate observations to create spatially uniform and temporally complete fields, and shows how uncertainty in predicted precipitation fields is propagated into ecological model results and that this propagation had different modes.

A nonparametric multiple choice method within the random utility framework

JOURNAL OF ECONOMETRICS, 97(2), 207–225.

By: J. Huang* & D. Nychka n

author keywords: polychotomous choices; cubic smoothing splines; random utility model; welfare measurement; nonmarket valuation
TL;DR: This paper proposes a nonparametric multiple choice model that applies the penalized likelihood method within the random utility framework, and demonstrates the model by applying it to nonmarket valuation of recreation sites. (via Semantic Scholar)

An algorithm for the construction of spatial coverage designs with implementation in SPLUS

COMPUTERS & GEOSCIENCES, 24(5), 479–488.

By: J. Royle* & D. Nychka n

author keywords: spatial design; space-filling designs; spatial statistics; spatial sampling; network design
TL;DR: An efficient algorithm for the construction of coverage designs is presented and its performance in terms of computation time and effectiveness at finding “good” designs is evaluated, suggesting that near-optimal designs for reasonably large problems can be computed efficiently.

1998 journal article

Noise and nonlinearity in measles epidemics: Combining mechanistic and statistical approaches to population modeling

AMERICAN NATURALIST, 151(5), 425–440.

By: S. Ellner n, B. Bailey n, G. Bobashev n, A. Gallant*, B. Grenfell* & D. Nychka*

author keywords: population dynamics; modeling; measles; time-series analysis; local Lyapunov exponents
TL;DR: The semimechanistic models used to analyze population dynamics data using historical data on measles epidemics are found to have better forecasting accuracy than either of the model types used in previous analyses when tested on data not used to fit the models. (via Semantic Scholar)
