Hierarchical models for semi-competing risks data with application to quality of end-of-life care for pancreatic cancer.

Journal of the American Statistical Association

Lee KH, Dominici F, Schrag D, Haneuse S.
PMID: 28303074
J Am Stat Assoc. 2016;111(515):1075-1095. doi: 10.1080/01621459.2016.1164052. Epub 2016 Oct 18.

Readmission following discharge from an initial hospitalization is a key marker of quality of health care in the United States. For the most part, readmission has been studied among patients with 'acute' health conditions, such as pneumonia and heart...

Penalized solutions to functional regression problems.

Computational statistics & data analysis

Harezlak J, Coull BA, Laird NM, Magari SR, Christiani DC.
PMID: 18552972
Comput Stat Data Anal. 2007 Jun 15;51(10):4911-4925. doi: 10.1016/j.csda.2006.09.034.

Recent technological advances in continuous biological monitoring and personal exposure assessment have led to the collection of subject-specific functional data. A primary goal in such studies is to assess the relationship between the functional predictors and the functional responses....

Bayesian Semi-parametric Analysis of Semi-competing Risks Data: Investigating Hospital Readmission after a Pancreatic Cancer Diagnosis.

Journal of the Royal Statistical Society. Series C, Applied statistics

Lee KH, Haneuse S, Schrag D, Dominici F.
PMID: 25977592
J R Stat Soc Ser C Appl Stat. 2015 Feb 01;64(2):253-273. doi: 10.1111/rssc.12078.

In the U.S., the Centers for Medicare and Medicaid Services uses 30-day readmission, following hospitalization, as a proxy outcome to monitor quality of care. These efforts generally focus on treatable health conditions, such as pneumonia and heart failure. Expanding...

Marginalized zero-altered models for longitudinal count data.

Statistics in biosciences

Tabb LP, Tchetgen EJ, Wellenius GA, Coull BA.
PMID: 27867423
Stat Biosci. 2016 Oct;8(2):181-203. doi: 10.1007/s12561-015-9136-6. Epub 2015 Sep 22.

Count data often exhibit more zeros than predicted by common count distributions like the Poisson or negative binomial. In recent years, there has been considerable interest in methods for analyzing zero-inflated count data in longitudinal or other correlated data...

Using Wavelet-Based Functional Mixed Models to Characterize Population Heterogeneity in Accelerometer Profiles: A Case Study.

Journal of the American Statistical Association

Morris JS, Arroyo C, Coull BA, Ryan LM, Herrick R, Gortmaker SL.
PMID: 19169424
J Am Stat Assoc. 2006 Dec 01;101(476):1352-1364. doi: 10.1198/016214506000000465.

We present a case study illustrating the challenges of analyzing accelerometer data taken from a sample of children participating in an intervention study designed to increase physical activity. An accelerometer is a small device worn on the hip that...

The importance of scale for spatial-confounding bias and precision of spatial regression estimators.

Statistical science : a review journal of the Institute of Mathematical Statistics

Paciorek CJ.
PMID: 21528104
Stat Sci. 2010 Feb;25(1):107-125. doi: 10.1214/10-STS326.

Residuals in regression models are often spatially correlated. Prominent examples include studies in environmental epidemiology to understand the chronic health effects of pollutants. I consider the effects of residual spatial structure on the bias and precision of regression coefficients,...

NONLINEAR PREDICTIVE LATENT PROCESS MODELS FOR INTEGRATING SPATIO-TEMPORAL EXPOSURE DATA FROM MULTIPLE SOURCES.

The annals of applied statistics

Bliznyuk N, Paciorek CJ, Schwartz J, Coull B.
PMID: 29861821
Ann Appl Stat. 2014 Sep;8(3):1538-1560. doi: 10.1214/14-AOAS737. Epub 2014 Oct 23.

Spatio-temporal prediction of levels of an environmental exposure is an important problem in environmental epidemiology. Our work is motivated by multiple studies on the spatio-temporal distribution of mobile source, or traffic related, particles in the greater Boston area. When...
