Richard Hudson and Norman Kaplan on the Coalescent Process.
MANY important questions in genetics involve looking back in time using data sampled in the present. The coalescent process describes the ancestry of a sample of genes: as lineages trace back, they coalesce at a rate inversely proportional to the effective population size. This remarkably simple approximation now dominates population genetics, both because it gives a direct intuition into the e...
متن کاملNorman Geschwind
Norman Geschwind (1926–1984) was born in New York City on 8 January, 1926, where his parents, Hannah and Morris, had arrived from Polish Galicia 20 years before [4]. When Norman was four, his father died of pneumonia. Despite difficulties, Hannah sent Norman and his brother Irving to the Hebrew Institute of Borough Park, where he never mastered Hebrew [2]. His later years at the Boy’s High Scho...

متن کاملNorman Pace
British species; the speckled wood (Pararge aegeria) and the gatekeeper or hedge brown (Pyronia tithonus). The researchers have looked at the patterns of genetic variation in these two species, both of which have been expanding their British distributions over the past 60 years. Both species have broadly similar dispersal ability, the researchers note, but differ in their habitat requirements. ...
متن کاملKaplan–Meier Estimator
The Kaplan–Meier estimator is a nonparametric estimator which may be used to estimate the survival distribution function from censored data. The estimator may be obtained as the limiting case of the classical actuarial (life table) estimator, and it seems to have been first proposed by Böhmer [2]. It was, however, lost sight of by later researchers and not investigated further until the importa...
