W.W. Howells' craniometric data

Description

Archaeological data on skulls.

Original data are described in a paper Howells (1996). Subset of these original data presented here is also used for some illustrations in the book Regrese by Karel Zvára (Zvára, 2008).

Two measurements are provided here: (i) occipital angle (týlní úhel in Czech), (ii) glabell-occipital length (největší délka mozkovny in Czech), and data from three sites: Berg in Austria, Australia and Burjati in Siberia. Further, two dataframes are provided: HowellsAll which contains all measurements reported by Howells and Howells which is a balanced (with respect to gender and site) random subset of original data.
