Tajima's D is a population genetic test statistic created by and named after the Japanese researcher Fumio Tajima. [1] Tajima's D is computed as the difference between two measures of genetic diversity: the mean number of pairwise differences and the number of segregating sites, each scaled so that they are expected to be the same in a neutrally evolving population of constant size.
These included the mean and the variance of the time between the present and the most recent common ancestor. In his paper, Tajima showed that well-known results of "classical" population genetics could be reproduced by using coalescence theory. While doing so, Tajima was likely unaware of the previous work of John Kingman in the same area. [5]
Master/slave: A consensual relationship where people enter a D/s dynamic with a focus on service and obedience. [63] This may be part of a 24/7 lifestyle and/or multiple scenes. A collaring ceremony may be performed where a Master symbolically or literally places a collar on the slave to establish "ownership", often around the neck or wrists ...

Fay and Wu's H is a statistical test created by and named after two researchers Justin Fay and Chung-I Wu. [1] The purpose of the test is to distinguish between a DNA sequence evolving randomly ("neutrally") and one evolving under positive selection.
This is a list of Latin words with derivatives in English language. Ancient orthography did not distinguish between i and j or between u and v. [1] Many modern works distinguish u from v but not i from j. In this article, both distinctions are shown as they are helpful when tracing the origin of English words.

Tajima's D is based on the expectation that S = theta * x where x is the sum of 1/i for i from 1 to N. Thus, we turn this into a method to estimate theta by noting that theta = E(S)/x. The current version suggests that S/x part is a "normalized" version of segregating sites, and this leads to a mistake in the calculation of D in the example.
