Software

Artemis Toumazi , Moreno Ursino and Sarah Zohar, INSERM, Paris. (10 August 2016). R package dfpk "A Bayesian Dose-Finding Design using Pharmacokinetics (PK) for Phase I Clinical Trials". Available at: https://cran.r-project.org/web/packages/dfpk/index.html 

Christian Roever, University Medical Centre, Gottingen. (16 December 2015). Available at: http://cran.r-project.org/package=bayesmeta. The bayesmeta package provides a collection of functions to facilitate easy Bayesian inference in the generic random-effects meta-analysis model. It allows to derive the posterior distribution of the two parameters (effect and heterogeneity), and provides the functionality to evaluate joint and marginal posterior probability distributions, predictive distributions, shrinkage, etc.
