Linkage Rate: The linkage rate is calculated as the percentage of owner records with accepted links to the database shown. It is the denominator for the false discovery rate (FDR). While it is not a data quality indicator alone, in addition to the FDR and the false negative error rate (FNR) it provides a complete picture of the overall linkage quality.
