BlockedInfinitySparseMatrix-class

Blocked Infinity Sparse Matrices are similar to Infinity Sparse Matrices, but they also keep track of the groups of units via an additional slot, <code>groups</code>

Distance based bipartite matching using minimum cost flow, oriented
to matching of treatment and control groups in observational studies ('Hansen'
and 'Klopfer' 2006 <doi:10.1198/106186006X137047>). 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.
