Talk:Wrapped distribution

Multivariate?
As yet, no inducation of how a multivariate wrapped distribution (mentioned in the lead) is constructed. Melcombe (talk) 09:46, 5 July 2011 (UTC)

The formula currently proposed as a multivariate extension

p_w(\vec\theta)=\sum_{k_1,...,k_F=-\infty}^{\infty}{p(\vec\theta+2\pi k_1\mathbf{e}_1+\dots+2\pi k_F\mathbf{e}_F)} $$ defines a distribution on the $$n$$-dimensional torus, not on the $$n$$-sphere. Compare with formula (1.1) in Hartman & Watson, ""Normal" distribution functions on spheres and the modified Bessel functions", Annals of Probability, 1974, Vol. 2, No. 4, 593-60.
