Using simulation studies to evaluate statistical methods
Tim P Morris, Ian R White, Michael J Crowther
Simulation studies are computer experiments that involve creating data by pseudorandom sampling. The key strength of simulation studies is the ability to understand the behaviour o…
Multiple imputation in Cox regression when there are time-varying effects of exposures
Ruth H. Keogh, Tim P. Morris
In Cox regression it is sometimes of interest to study time-varying effects (TVE) of exposures and to test the proportional hazards assumption. TVEs can be investigated with log ha…
A matrix-based method of moments for fitting multivariate network meta-analysis models with multiple outcomes and random inconsistency effects
Dan Jackson, Sylwia Bujkiewicz, Martin Law +2
Random-effects meta-analyses are very commonly used in medical statistics. Recent methodological developments include multivariate (multiple outcomes) and network (multiple treatme…
A mean score method for sensitivity analysis to departures from the missing at random assumption in randomised trials
Ian R. White, James Carpenter, Nicholas J. Horton
Most analyses of randomised trials with incomplete outcomes make untestable assumptions and should therefore be subjected to sensitivity analyses. However, methods for sensitivity…
LiftUpp: Support to develop learner performance
Frans A. Oliehoek, Rahul Savani, Elliot Adderton +8
Various motivations exist to move away from the simple assessment of knowledge towards the more complex assessment and development of competence. However, to accommodate such a cha…
MultiBUGS: A parallel implementation of the BUGS modelling framework for faster Bayesian inference
Robert J. B. Goudie, Rebecca M. Turner, Daniela De Angelis +1
MultiBUGS (https://www.multibugs.org) is a new version of the general-purpose Bayesian modelling software BUGS that implements a generic algorithm for parallelising Markov chain Mo…
