Turn up the Heat! A Tutorial for the MAGMA R-package.

The MAGMA-package offers nearest neighbor matching for two to four groups. It also includes the option to match data of a 2x2 Design. In addition, MAGMA includes a framework for evaluating the post-matching balance. This vignette is a tutorial on MAGMA. It demonstrates the main MAGMA function on an included simulated dataset. In total, this vignette includes a two-group, a three-group, and a 2x2-design which is approximately equivalent to a four-group example. This three examples are conducted in a standard matching process, as well as with exact matching. Parts of this tutorial are also included in the respective help pages of the functions. For details of the algorithm and a more extensive introduction of MAGMA, see Feuchter et al. (2022).
