a-ratio | r_{i} |
the probability that the values in the
corresponding fields of two records being compared will agree if the records are matched
(cf. reliability); the a. for a field may be different for each specific value
possible or it may be value non-specific; H. B. Newcombe calls this the numerator of the
frequency ratio in the case of agreement — for disagreement the quantity 1 – a.
may be the numerator (cf. ratio) (cf. Newcombe, 1967, p. 21). |
