robustus: Australopithecus robustus molar size

Description

Australopithecus robustus are early hominids from Africa. The molar size is assumed to be larger in males than female, these data can therefore be used with a mixture model in a study on sexual dimorphism.

Usage

data(robustus)

Format

'robustus' is a vector with 36 observations on the breadth (mm) of the lower first molar of Australopithecus robustus.
