Abstract: This article introduces two new commands, smpc and smmatch, that implement the statistical matching procedure proposed by Rubin (1986, Journal of Business and Economic Statistics 4: 87–94). The purpose of statistical matching in Rubin’s procedure is to generate a single dataset from various datasets, where each dataset contains a specific variable of interest and all contain some variables in common. For two variables of interest that are not observed jointly for any unit, smpc generates the predicted values of each as a function of the other vari- able of interest and a set of control variables by assuming a partial correlation value (defined by the user) between the two variables of interest (other statistical matching procedures assume that they are conditionally independent given the control variables). The smmatch command, on the other hand, matches observations of different datasets according to their predicted values (using a minimum distance criterion) conditional on a set of control variables, and it imputes the observed value of the match for the missing.
