Build Status Build Status (develop)

GeMTC is an R package for Network Meta-Analysis (also know as Mixed Treatment Comparison, MTC) model generation.


Use R CMD build gemtc to build the R package. The Makefile offers a number of targets for convenience, but is entirely optional. Use make install to both build and install the package.

You will need a working installation of rjags, which in turn requires a working installation of JAGS.


The testthat package is used for testing. Tests reside in the tests/testthat directory. There are three levels of tests:

  • unit: unit tests - these test relatively isolated pieces of functionality and should be fast to run. They will be run by make test or R CMD check.

  • regress: regression tests exercise full code paths, and typically run all code that an analyst would run on a given dataset. They aim to catch bugs in existing functionality due to the introduction of new code. They should not take very long to run, and do not aim to produce reasonable posterior estimates. These can be run using make regress.

  • validate: valition tests verify the posterior summaries obtained by the R package against results that were previously (manually) checked against results published in the literature. They typically take very long to run, and are probabilistic in nature. Many individual comparisons are made, so a couple of failures over the entire test suite are to be expected. However, these should not be systematic. These tests can be run using make validate.
