Journal ArticleDOI
Conservative prior distributions for variance parameters in hierarchical models
TL;DR: The authors proposed a conservative prior distribution for variance components, which deliberately gives more weight to smaller values and is appropriate for investigators who are skeptical about the presence of variability in the second-stage parameters (random effects).
Journal ArticleDOI
An overview of robust Bayesian analysis
James O. Berger,Elías Moreno,Luis R. Pericchi,M. Jesús Bayarri,José M. Bernardo,Juan Antonio Cano,Julián de la Horra,Jacinto Martín,David Rios-Insua,Bruno Betrò,Anirban DasGupta,Paul Gustafson,Larry Wasserman,Joseph B. Kadane,Cid Srinivasan,Michael Lavine,Anthony O'Hagan,Wolfgang Polasek,Christian P. Robert,Constantinos Goutis,Fabrizio Ruggeri,G. Salinetti,Siva Sivaganesan +22 more
TL;DR: An overview of the subject of robust Bayesian analysis is provided, one that is accessible to statisticians outside the field, and recent developments in the area are reviewed.
Book
Measurement Error and Misclassification in Statistics and Epidemiology: Impacts and Bayesian Adjustments
TL;DR: In this paper, the authors discuss the impact of MISMEASURED CATEGORICAL VARIABLES on Odds-Ratios and the effect of Mismeasurement bias on the performance of MIS-based models.
Journal ArticleDOI
Association Between Use of Interferon Beta and Progression of Disability in Patients With Relapsing-Remitting Multiple Sclerosis
Afsaneh Shirani,Yinshan Zhao,Mohammad Ehsanul Karim,Charity Evans,Elaine Kingwell,Mia L. van der Kop,Joel Oger,Paul Gustafson,John Petkau,Helen Tremlett +9 more
TL;DR: Exposure to interferon beta was not associated with a statistically significant difference in the hazard of reaching an EDSS score of 6 when either the contemporary control cohort or the historical control cohort was considered, and propensity score adjustment did not substantially change the results.
Journal ArticleDOI
On Model Expansion, Model Contraction, Identifiability and Prior Information: Two Illustrative Scenarios Involving Mismeasured Variables
TL;DR: In this paper, the authors compare the merits of model contraction and model expansion, and investigate whether it is necessarily a good idea to alter the model for the sake of identifiability.
