Statistical Software Components from Boston College Department of Economics

Abstract: mahapick seeks matching "control" observations for a set of "treated" observations. mahascore and mahascores compute the distance measures. covariancemat creates a matrix of covariances. variancemat creates a matrix of variances. screenmatches and stackids are ancillary programs for handling the output of mahapick.
