v3.0 beta [Aug 21, 2013]
- Removes the limitation on the number of records included in file 2; the program works for any number of records in file 2 as long as the computer has sufficient memory to read in data from file 1, which has a limit of 4.5–4.8 million records.
- Provides a Best Match option to choose whether to write all potential matches (many:many linkages) or only the matches with the highest score to the linkage report (one:many linkages).
- Allows users to choose whether to output a non-match file.
- Provides confirmation-like method for variables like address that contribute positive weight for the linkage score with agreement, but 0 weight with disagreement.
- Provides Social Security number-like matching method for a generic ID.
- Provides a new name matching method that is more robust against the frequency of names or outlier names such as misspelled names.
- Allows variables to be selected as matching variables multiple times to perform array comparisons automatically.
- Allows users to provide their own name frequency files for use by name matching methods.
