Contains a suite of functions for health economic evaluations with missing outcome data. The package can fit different types of statistical models under a fully Bayesian approach using Markov Chain Monte Carlo (MCMC) methods. Three classes of models can be fitted under a variety of missing data assumptions: selection models, pattern mixture models and hurdle models. In addition to model fitting,
missingHE provides a set of specialised functions to assess model convergence and summarise the statistical and economic results using different types of measures and graphs.
There are two ways of installing
missingHE. A "stable" version is packaged and binary files are available for Windows and as source. To install the stable version on a Windows machine, run the following command
which installs the package from a CRAN mirror and ensures that
install.packages() can also install the "dependencies" (e.g. other packages that are required for
missingHE to work).
It is also possible to install
missingHE using the "development" version - this will usually be updated frequently and may be continuously tested. On Windows machines, you need to install a few dependencies, including Rtools first, e.g. by running
pkgs <- c("R2jags","ggplot2","gridExtra","BCEA","ggmcmc","loo","Rtools","devtools", "utils") repos <- c("https://cran.rstudio.com") install.packages(pkgs,repos=repos,dependencies = "Depends")
before installing the package using
devtools::install_github("AnGabrio/missingHE", build_vignettes = TRUE)
The optional argument
build_vignettes = TRUE allows to install the vignettes of the package locally on your computer. These consist in brief tutorials to guide the user on how to use and customise the models in
missingHE using different functions of the package. Once the package is installed, they can be accessed using the command
utils::browseVignettes(package = "missingHE")
which shows all the vignettes available for the package.
All models implemented in
missingHE are written in the BUGS language using the software JAGS, which needs to be installed from its own repository and instructions for installations under different OS can be found online. Once installed, the software is called in
missingHE via the R package R2jags.
Note that the
missingHE package is currently under active development and therefore it is advisable to reinstall the package directly from GitHub before each use to ensure that you are using the most updated version.
