The relative rate test is a genetic comparative test between two ingroups (somewhat closely related species) and an outgroup or “reference species” to compare mutation and evolutionary rates between the species. [1]
This constituted a relative rate test of molecular change, and showed that both human and chimpanzee albumin lineages must have accumulated approximately equal amounts of change since their common ancestor (else one would be more different from the outgroup monkeys than the other), thereby providing direct empirical evidence of an approximate ...
This method is known as the relative rate test. Sarich and Wilson's paper reported, for example, that human (Homo sapiens) and chimpanzee (Pan troglodytes) albumin immunological cross-reactions suggested they were about equally different from Ceboidea (New World Monkey) species (within experimental error). This meant that they had both ...
In MEGA, this test is performed by applying a maximum likelihood test to a given tree topology and sequence alignment. This produces two log-likelihood values, one with the clock hypothesis and one without. [35] Another approach offered by MEGA is Tajima's relative rate test. This method compares the number of substitutions per site between ...
A highly indicative test of changes in allele frequencies is the QTL sign test, and other tests include the Ka/Ks ratio test and the relative rate test. The QTL sign test compares the number of antagonistic QTL to a neutral model, and allows for testing of directional selection against genetic drift. [11]

Another theory is that your basal metabolic rate—the calories your body burns at rest—drops as you lose weight. This shift can shrink your calorie deficit, making it harder to shed pounds.
The likelihood-ratio test, also known as Wilks test, [2] is the oldest of the three classical approaches to hypothesis testing, together with the Lagrange multiplier test and the Wald test. [3] In fact, the latter two can be conceptualized as approximations to the likelihood-ratio test, and are asymptotically equivalent.
