On random sequences with spherical symmetry
J. F. C. KINGMAN
University of Oxford
An infinite sequence of random variables, any finite sample from which has a spherically symmetric joint distribution, is shown to have the property that, conditional on a further random variable V, the variables are independent with the same normal distribution N(0, V).
Key Words: Exchangeable Spherical symmetry Conditional independence Normal distribution
