The caliper is optimal in the sense that\nit is as small as possible such that a matching exists. The\nmain functions in the 'bigmatch' package are optcal() to find\nthe optimal caliper, optconstant() to find the optimal number\nof nearest neighbors, and nfmatch() to find a near-fine balance\nmatch with a caliper and a restriction on the number of nearest\nneighbors.
