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.
