  • It's interesting that, in multivariate analysis, (an important branch of statistics that deals with the treatment of data consisting of multiple, possibly correlated, measurements, usually considered as response variables) one of the canonical datasets used to illustrate the various methods of analysis is a collection of anthropometric cranial measurements. Sir Ronald Aylmer Fisher, the great grumpy old grandfather of modern statistics, had a field day with them, as did many of his disciples.

    This was before the vile, contemptible "psychometricians" moved in and sullied the entire field with their ridiculous fripperies such as "factor analysis", "correspondence analysis" (a uniquely French perversion) and other forms of black magic too infandous to be named here.
