Elliptically symmetric distributions for directional data of arbitrary dimension

Z Yu, X Huang - arxiv preprint arxiv:2212.05634, 2022 - arxiv.org
We formulate a class of angular Gaussian distributions that allows different degrees of
isotropy for directional random variables of arbitrary dimension. Through a series of novel …
