The Link King 4.2

The Link King 4.2 is a powerful program that can record Linkage and Consolidation Software (powered by SAS/AF)

In the realm of public domain software for record linkage and unduplication (aka. dedupe software), The Link King reigns supreme. The Link King has fashioned a powerful alliance between sophisticated probabilistic record linkage and deterministic record linkage protocols Incorporating features unavailable in many proprietary record linkage programs.

Major Features:

1. The Link King’s probabilistic record linkage protocol was adapted from the algorithm developed by MEDSTAT for the Substance Abuse and Mental Health Services Administration’s (SAMHSA) Integrated Database Project. The deterministic record linkage protocols were developed at
2. Washington State’s Division of Alcohol and Substance Abuse for use in a variety of evaluation and research projects.
3. The Link King’s graphical user interface (GUI) makes record linkage and unduplication easy for beginning and advanced users. The data linking neophyte will appreciate the easy-to-follow instructions.
4. The Link Kings artificial intelligence will assist in the selection of the most appropriate linkage/unduplication protocol.
5. The technical wizard will appreciate the discussion of data linkage/unduplication issues in The Link King’s user manual, the variety of user-specified options for blocking and linkage decisions, and the powerful interface for manual review of “uncertain” linkages.
6. The Link King requires a base SAS license but NO SAS programming experience. If you have a SAS dataset, The Link King can do the rest.
7. The Link King prefers SAS v9.0 or higher but is comfortable with SAS v8.
