A Bayesian Approach to Graphical Record Linkage and Deduplication
(Journal of the American Statistical Association, 20161001)© 2016 American Statistical Association.We propose an unsupervised approach for linking records across arbitrarily many files, while simultaneously detecting duplicate records within files. Our key innovation involves the ... 
A branching process model for flow cytometry and budding index measurements in cell synchrony experiments.
(Ann Appl Stat, 2009)We present a flexible branching process model for cell population dynamics in synchrony/timeseries experiments used to study important cellular processes. Its formulation is constructive, based on an accounting of the unique ... 
A Cheegertype inequality on simplicial complexes
(ADVANCES IN APPLIED MATHEMATICS, 201405) 
A Digital Network Approach to Infer Sex Behavior in Emerging HIV Epidemics
(PLOS ONE, 20140703) 
A dimensionless number for understanding the evolutionary dynamics of antigenically variable RNA viruses.
(Proc Biol Sci, 20111222)Antigenically variable RNA viruses are significant contributors to the burden of infectious disease worldwide. One reason for their ubiquity is their ability to escape herd immunity through rapid antigenic evolution and ... 
A Dynamic Directional Model for Effective Brain Connectivity using Electrocorticographic (ECoG) Time Series.
(J Am Stat Assoc, 20150301)We introduce a dynamic directional model (DDM) for studying brain effective connectivity based on intracranial electrocorticographic (ECoG) time series. The DDM consists of two parts: a set of differential equations describing ... 
A Foxp2 Mutation Implicated in Human Speech Deficits Alters Sequencing of Ultrasonic Vocalizations in Adult Male Mice.
(Front Behav Neurosci, 2016)Development of proficient spoken language skills is disrupted by mutations of the FOXP2 transcription factor. A heterozygous missense mutation in the KE family causes speech apraxia, involving difficulty producing words ... 
A note on Bayesian inference after multiple imputation
(American Statistician, 20100501)This article is aimed at practitioners who plan to use Bayesian inference on multiplyimputed datasets in settings where posterior distributions of the parameters of interest are not approximately Gaussian. We seek to steer ... 
A phylogenetic transform enhances analysis of compositional microbiota data.
(Elife, 20170215)Surveys of microbial communities (microbiota), typically measured as relative abundance of species, have illustrated the importance of these communities in human health and disease. Yet, statistical artifacts commonly plague ... 
A practical criterion for positivity of transition densities
(Nonlinearity, 20150710)© 2015 IOP Publishing Ltd & London Mathematical Society.We establish a simple criterion for locating points where the transition density of a degenerate diffusion is strictly positive. Throughout, we assume that the diffusion ... 
A theory of hypoellipticity and unique ergodicity for semilinear stochastic PDEs
(Electronic Journal of Probability, 20110509)We present a theory of hypoellipticity and unique ergodicity for semilinear parabolic stochastic PDEs with "polynomial" nonlinearities and additive noise, considered as abstract evolution equations in some Hilbert space. ... 
A weak trapezoidal method for a class of stochastic differential equations
(Communications in Mathematical Sciences, 20110301)We present a numerical method for the approximation of solutions for the class of stochastic differential equations driven by Brownian motions which induce stochastic variation in fixed directions. This class of equations ... 
Accommodating the ecological fallacy in disease mapping in the absence of individual exposures.
(Stat Med, 20170919)In health exposure modeling, in particular, disease mapping, the ecological fallacy arises because the relationship between aggregated disease incidence on areal units and average exposure on those units differs from the ... 
Adaptive Mixture Modelling Metropolis Methods for Bayesian Analysis of Nonlinear StateSpace Models.
(J Comput Graph Stat, 20100601)We describe a strategy for Markov chain Monte Carlo analysis of nonlinear, nonGaussian statespace models involving batch analysis for inference on dynamic, latent state variables and fixed model parameters. The key innovation ... 
An elementary proof of the existence and uniqueness theorem for the NavierStokes equations
(Communications in Contemporary Mathematics, 19991101) 
An Empirical Comparison of Multiple Imputation Methods for Categorical Data
(The American Statistician, 20170403)© 2017 American Statistical Association. Multiple imputation is a common approach for dealing with missing values in statistical databases. The imputer fills in missing values with draws from predictive models estimated ... 
Association between DNA Damage Response and Repair Genes and Risk of Invasive Serous Ovarian Cancer
(PLOS ONE, 20100408) 
Association between DNA damage response and repair genes and risk of invasive serous ovarian cancer.
(PLoS One, 20100408)BACKGROUND: We analyzed the association between 53 genes related to DNA repair and p53mediated damage response and serous ovarian cancer risk using casecontrol data from the North Carolina Ovarian Cancer Study (NCOCS), ... 
Asymptotic coupling and a general form of Harris' theorem with applications to stochastic delay equations
(Probability Theory and Related Fields, 20110301)There are many Markov chains on infinite dimensional spaces whose onestep transition kernels are mutually singular when starting from different initial conditions. We give results which prove unique ergodicity under minimal ...
