vmatch

Computerized matching of cases to controls using variable optimal matching. The number of controls per case is allowed to vary with only the total fixed. Controls may be matched to cases using one or more factors (X’s). VMATCH uses the case/controls distance matrix as input. This distance matrix can be calculated using the DIST macro, which includes an optional call to VMATCH. For SAS V9.3 and higher. Erik Bergstralh & Jon Kosanke. [03/2004]
