validDistanceSpecification

distance

If <code>TRUE</code> (default) the function will
raise an error for invalid objects. Otherwise, it returns a
logical.

The functions <code><a rd-options="" href="/link/fullmatch?package=optmatch&version=0.9-17" data-mini-rdoc="optmatch::fullmatch">fullmatch</a></code> and <code><a rd-options="" href="/link/pairmatch?package=optmatch&version=0.9-17" data-mini-rdoc="optmatch::pairmatch">pairmatch</a></code>
create optimal matches of treated and control units given a
matrix (or similar representation) of distances between treated and
control units. These distance specifications must implement certain
generic functions. This function checks that all necessary methods
exist and the object can be used to specify distances in a way that
the matching functions can use.

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.

Functions for Optimal Matching

validDistanceSpecification function

The functions <code><a rd-options='' href='fullmatch'>fullmatch</a></code> and <code><a rd-options='' href='pairmatch'>pairmatch</a></code>
create optimal matches of treated and control units given a
matrix (or similar representation) of distances between treated and
control units. These distance specifications must implement certain
generic functions. This function checks that all necessary methods
exist and the object can be used to specify distances in a way that
the matching functions can use.

validDistanceSpecification: (Internal) Validate that objects are valid distance specifications.
