Estimation of Contextual Exposure to HIV from GPS Data
Haoyang Wu, Zhaoxing Wu, Thulile Mathenjwa +10
We present a comprehensive statistical methodological framework for estimating contextual exposure to HIV that includes local (grid-cell level) estimation of HIV prevalence and hum…
Bayesian Inference for Single-factor Graphical Models
David Marcano, Adrian Dobra
We introduce efficient MCMC algorithms for Bayesian inference for single-factor models with correlated residuals where the residuals' distribution is a Gaussian graphical model. We…
Modeling Human Spatial Mobility Patterns with the Lévy Flight Cluster Model
Malcolm Wolff, Adrian Dobra, Anton H. Westveld +1
Despite the extensive collection of individual mobility data over the past decade, fueled by the widespread use of GPS-enabled personal devices, the existing statistical literature…
A statistical framework for analyzing activity pattern from GPS data
Haoyang Wu, Yen-Chi Chen, Adrian Dobra
We introduce a novel statistical framework for analyzing the GPS data of a single individual. Our approach models daily GPS observations as noisy measurements of an underlying rand…
