Markov chain Monte Carlo methods and the label switching problem in Bayesian mixture modeling

A Jasra, CC Holmes, DA Stephens - 2005 - projecteuclid.org
In the past ten years there has been a dramatic increase of interest in the Bayesian analysis
of finite mixture models. This is primarily because of the emergence of Markov chain Monte …

[HTML][HTML] Treatment dose-response in amblyopia therapy: the Monitored Occlusion Treatment of Amblyopia Study (MOTAS)

CE Stewart, MJ Moseley, DA Stephens… - … & visual science, 2004 - arvojournals.org
purpose. Amblyopia is the commonest visual disorder of childhood. Yet the contributions of
the two principal treatments (spectacle wear and occlusion) to outcome are unknown. This …

Bayesian retrospective multiple‐changepoint identification

DA Stephens - Journal of the Royal Statistical Society: Series C …, 1994 - Wiley Online Library
Changepoint identification is important in many data analysis problems, such as industrial
control and medical diagnosis–given a data sequence, we wish to make inference about the …

Demystifying optimal dynamic treatment regimes

EEM Moodie, TS Richardson, DA Stephens - Biometrics, 2007 - academic.oup.com
A dynamic regime is a function that takes treatment and covariate history and baseline
covariates as inputs and returns a decision to be made. Murphy (2003, Journal of the Royal …

Development of a cross-platform biomarker signature to detect renal transplant tolerance in humans

…, B Sawitzki, S Tomiuk, DA Stephens… - The Journal of …, 2010 - Am Soc Clin Investig
Identifying transplant recipients in whom immunological tolerance is established or is developing
would allow an individually tailored approach to their posttransplantation management. …

On population-based simulation for static inference

A Jasra, DA Stephens, CC Holmes - Statistics and Computing, 2007 - Springer
In this paper we present a review of population-based simulation for static inference problems.
Such methods can be described as generating a collection of random variables {X n } n=1,…

Objectively monitored patching regimens for treatment of amblyopia: randomised trial

CE Stewart, DA Stephens, AR Fielder, MJ Moseley - Bmj, 2007 - bmj.com
Objectives To compare visual outcome in response to two prescribed rates of occlusion (six
hours a day and 12 hours a day). Design Unmasked randomised trial. Setting Research …

[HTML][HTML] Treatment of unilateral amblyopia: factors influencing visual outcome

CE Stewart, AR Fielder, DA Stephens… - … & visual science, 2005 - arvojournals.org
purpose. To identify factors that influence the outcome of treatment for unilateral amblyopia,
as a part of the Monitored Occlusion Treatment of Amblyopia Study (MOTAS). methods. This …

Triiodothyronine stimulates food intake via the hypothalamic ventromedial nucleus independent of changes in energy expenditure

…, JV Gardiner, IP Connoley, DA Stephens… - …, 2004 - academic.oup.com
Increased food intake is characteristic of hyperthyroidism, although this is presumed to
compensate for a state of negative energy balance. However, here we show that the thyroid …

Inference for Lévy‐driven stochastic volatility models via adaptive sequential Monte Carlo

A Jasra, DA Stephens, A Doucet… - … Journal of Statistics, 2011 - Wiley Online Library
We investigate simulation methodology for Bayesian inference in Lévy‐driven stochastic
volatility (SV) models. Typically, Bayesian inference from such models is performed using …
