Abstract: A computing device (e.g., a server or other type of computer) electronically receives multiple target records from a client and determines which records of the target list matches records of a database. The matched records of the database include one or more additional fields that are not contained in the target records received from the client. The computing device models the relationship among the matched records of the database with respect to the one or more additional fields. In one implementation, the computing device carries out this modeling by performing stepwise linear regression on the matched records of the database with respect to the one or more additional fields. The computing device uses the output of this modeling process in order to identify which of the one or more additional fields has a significant impact on the matching between the records of the target list and the records of the database.
