global frequency ratio the global frequency of a given comparison outcome among matched or truly linked records (cf. Reliability) compared to the corresponding frequency among random comparisons (cf. coincidence, general frequency); the g. f. r. always relates to the outcome of comparisons of non-specific values; the g. f. r. may be expressed as a field weight. (Cf. ratio) (Cf. Newcombe, 1988, p. 103).
