Mauchly, J.W. 1940. Significance test for sphericity of a
normal n-variate distribution. Annals of Mathematical
Statistics 11: 204-209.
For every person who thinks "Mauchly's test of sphericity"
there must be a hundred who think John W. Mauchly, principal
inventor with J. Presper Eckert of ENIAC and thus one of
the founders of modern computing...
