Analyze Data from Stepped Wedge Cluster Randomized Trials

Provide various functions and tools to help fit models for estimating treatment effects in stepped wedge cluster randomized trials. Implements methods described in Kenny, Voldal, Xia, and Heagerty (2022) "Analysis of stepped wedge cluster randomized trials in the presence of a time-varying treatment effect", .

steppedwedge

An R package for analyzing data from stepped wedge cluster randomized trials

Overview

steppedwedge is an open-source R package designed for analyzing data from stepped wedge cluster randomized trials. Functions are given for checking/visualizing datasets and estimating various treatment effect parameters, including the immediate treatment effect (ITE), exposure time averaged treatment effect (ETATE), calendar time averaged treatment effect (CTATE).

Installation

The latest stable version of steppedwedge can be installed from CRAN using install.packages():

install.packages("steppedwedge")

The current development version can be installed using devtools::install_github():

devtools::install_github(repo="Avi-Kenny/steppedwedge")
