%description
Perform non-bipartite matching and matched randomization. A "bipartite"
matching utilizes two separate groups, e.g. smokers being matched to
nonsmokers or cases being matched to controls. A "non-bipartite" matching
creates mates from one big group, e.g. 100 hospitals being randomized for
a two-arm cluster randomized trial or 5000 children who have been exposed
to various levels of secondhand smoke and are being paired to form a
greater exposure vs. lesser exposure comparison. At the core of a
non-bipartite matching is a N x N distance matrix for N potential mates.
The distance between two units expresses a measure of similarity or
quality as mates (the lower the better). The 'gendistance()' and
'distancematrix()' functions assist in creating this. The 'nonbimatch()'
function creates the matching that minimizes the total sum of distances
between mates; hence, it is referred to as an "optimal" matching. The
'assign.grp()' function aids in performing a matched randomization. Note
bipartite matching can be performed using the prevent option in
'gendistance()'.
