likelihood ratio

[′līk·lē‚hu̇d ‚rā·shō]
(statistics)
The probability of a random drawing of a specified sample from a population, assuming a given hypothesis about the parameters of the population, divided by the probability of a random drawing of the same sample, assuming that the parameters of the population are such that this probability is maximized.

This Part, therefore, defines and briefly describes the types of chromosomes, alleles, and loci used in forensic DNA identification and how these generate likelihood ratios for specific genetic relationships between individuals that can be used to produce investigative leads.
According to the analysis of GHQ score specific (multilevel) likelihood ratios (7), the latter was observed to have a value of less than one up to a cutoff score of 6 (Table 4) and more than one, at a score of [greater than or equal to] 7, for which the sensitivity was lower (64% : 95% CI: 56%-73%) and specificity (84% : 95% CI: 79%-88.
