caliperUpperBound

A numeric vector of scores providing 1-D position of units

scores

Width of caliper, must be positive.

width

Optional factor variable that groups the scores, as would
be used by <code><a rd-options="" href="/link/exactMatch?package=optmatch&version=0.9-17" data-mini-rdoc="optmatch::exactMatch">exactMatch</a></code>. Including structure allows for wider
calipers.

structure

(Internal) Returns a reasonable upper bound on the arcs remaining after placing a caliper.

internal

Distance based bipartite matching using the RELAX-IV minimum cost flow solver,
oriented to matching of treatment and control groups in observational
studies. Routines are provided to generate distances from generalised linear models (propensity
score matching), formulas giving variables on which to limit matched distances, stratified or
exact matching directives, or calipers, alone or in combination.
