Modeling Homophily in Dynamic Networks with Application to HIV Molecular Surveillance
V. DeGruttola, M. Nakazawa, J. Liu +3
This paper describes a novel approach to modeling homphily, i.e. the tendency of nodes that share (or differ in) certain attributes to be linked; we consider dynamic networks in wh…
Novel Methods for the Analysis of Stepped Wedge Cluster Randomized Trials
Lee Kennedy-Shaffer, Victor De Gruttola, Marc Lipsitch
Stepped wedge cluster randomized trials (SW-CRTs) have become increasingly popular and are used for a variety of interventions and outcomes, often chosen for their feasibility adva…
Bayesian method for inferring the impact of geographical distance on intensity of communication
Fei Li, Jukka-Pekka Onnela, Victor DeGruttola
Both theoretical models and empirical findings suggest that the intensity of communication among groups of people declines with their degree of geographical separation. There is so…
Bayesian reconstruction of HIV transmission trees from viral sequences and uncertain infection times
Hesam Montazeri, Susan Little, Niko Beerenwinkel +1
Genetic sequence data of pathogens are increasingly used to investigate transmission dynamics in both endemic diseases and disease outbreaks; such research can aid in development o…
Leveraging contact network structure in the design of cluster randomized trials
Guy Harling, Rui Wang, Jukka-Pekka Onnela +1
Background: In settings where proof-of-principle trials have succeeded but the effectiveness of different forms of implementation remains uncertain, trials that not only generate i…
Leveraging Contact Network Information in Clustered Randomized Studies of Contagion Processes
Maxwell H Wang, Patrick Staples, Mélanie Prague +2
In a randomized study, leveraging covariates related to the outcome (e.g. disease status) may produce less variable estimates of the effect of exposure. For contagion processes ope…
