%description
Attain excellent covariate balance by matching two treated units and one
control unit or vice versa within strata. Using such triples, as opposed
to also allowing pairs of treated and control units, allows easier
interpretation of the two possible weights of observations and better
insensitivity to unmeasured bias in the test statistic. Using triples
instead of matching in a fixed 1:2 or 2:1 ratio allows for the match to be
feasible in more situations. The 'rrelaxiv' package, which provides an
alternative solver for the underlying network flow problems, carries an
academic license and is not available on CRAN, but may be downloaded from
'GitHub' at <https://github.com/josherrickson/rrelaxiv/>. The 'Gurobi'
commercial optimization software is required to use the two functions
[infsentrip()] and [triplesIP()]. These functions are not essential to the
main purpose of this package. A free academic license can be obtained at
<https://www.gurobi.com/features/academic-named-user-license/>. The
'gurobi' R package can then be installed following the instructions at
<https://www.gurobi.com/documentation/9.1/refman/ins_the_r_package.html>.
