Conservative prior distributions for variance parameters in hierarchical models
Bayesian hierarchical models typically involve specifying prior distributions for one or more variance components. This is rather removed from the observed data, so specification based on expert… Expand
Three Measures of Forest Fire Smoke Exposure and Their Associations with Respiratory and Cardiovascular Health Outcomes in a Population-Based Cohort
Background: During the summer of 2003 numerous fires burned in British Columbia, Canada. Objectives: We examined the associations between respiratory and cardiovascular physician visits and hospital… Expand

Background: We developed and tested a new method, called the Evidence-based Practice for Improving Quality method, for continuous quality improvement. Methods: We used cluster randomization to assign… Expand
Current CHS and NHBPEP Criteria for Severe Preeclampsia Do Not Uniformly Predict Adverse Maternal or Perinatal Outcomes
Objective: To determine the association between adverse maternal/perinatal outcomes and Canadian and U.S. preeclampsia severity criteria. Methods: Using PIERS data (Preeclampsia Integrated Estimate… Expand
Autoregressive spatial smoothing and temporal spline smoothing for mapping rates.
This article proposes generalized additive mixed models for the analysis of geographic and temporal variability of mortality rates. This class of models accommodates random spatial effects and fixed… Expand
Proportional hazards frailty models for recurrent methadone maintenance treatment.
The authors' objective in this study was to identify determinants of time to discontinuation of methadone maintenance treatment (MMT) across multiple treatment episodes. Population-level data on drug… Expand
A conceptual model of water's role as a reservoir in Helicobacter pylori transmission: a review of the evidence.

- Epidemiology and infection
- 1 June 2006
Helicobacter pylori infection plays a role in the development of chronic gastritis, peptic ulcer and gastric cancer, yet the route of transmission into susceptible hosts remains unknown. Studies… Expand
On Gaussian Markov random fields and Bayesian disease mapping

- 1 February 2011
We discuss the nature of Gaussian Markov random fields (GMRFs) as they are typically formulated via full conditionals, also named conditional autoregressive or CAR formulations, to represent small… Expand
