Power analysis in cluster randomized trials

This is a research compendium containing all the scripts, manuscript, and illustrations used in the project “Sample Size Determination for Cluster Randomised Trials with the Bayes Factor”. The aim of this project was to develop a method and tools for sample size determination of cluster randomised trials when using the Approximated Adjusted Fractional Bayes Factor for hypothesis testing.

R package

This project is part of a bigger project named “Bayesian sample size calculation for trials with multilevel data”. All the functions developed to determine the sample size for cluster randomised trials are available in the R package SSDBayesML

Shiny App

In the manuscript can be seen a fraction of the simulation results given the limitations in space. For this reason, we have created a Shiny app in which is possible to explore the effects of different combinations of the intraclass correlation, Bayes factor threshold, cluster size, number of clusters, effect sizes and fractions of information (b).
