Let View the MathML source follow a spherically or elliptically symmetric distribution centered at zero, and Yi=Xi+1/X1, View the MathML source. It is shown that under spherical symmetry View the MathML source has a symmetric Cauchy distribution and under elliptical symmetry a general Cauchy distribution. Geometrically, View the MathML source is the tangent (or cotangent) vector of the polar angle θ1. The simple case of one ratio is treated in Arnold and Brockett (1992), Jones (1999, 2008). Moreover, it is shown that View the MathML source follows the tn−1 distribution, so that the normal theory distributions of Student’s t and correlation coefficient r hold under spherical symmetry.
