Fast Bayesian Record Linkage With Record-Specific Disagreement Parameters
Thomas Stringham
Abstract:Applied researchers are often interested in linking individuals between two datasets that lack unique identifiers. Accuracy and computational feasibility are a challenge, particularly when linking large datasets. We develop a Bayesian method for automated probabilistic record linkage and show it recovers 40% more true matches, holding accuracy constant, than comparable methods in a matching of Union Army recruitment data to the 1900 US Census for which expert-labelled true matches are known. Our approach, whic… Show more
