Record Linkage: Statistical Models for Matching Computer Records

J. B. Copas and F. J. Hilton

Journal of the Royal Statistical Society Series A, 1990, vol. 153, issue 3, 287-312

Abstract: We wish to measure the evidence that a pair of records relates to the same, rather than different, individuals. The paper emphasizes statistical models which can be fitted to a file of record pairs known to be correctly matched, and then used to estimate likelihood ratios. A number of models are developed and applied to UK immigration statistics. The combination of likelihood ratios for possibly correlated record fields is discussed.
