Abstract

Regular variation of the tail of a multivariate probability distribution is implied by regular variation of the density f provided f satisfies a regularity condition. We give a uniformity condition which controls variation of the function f across rays. Our condition is somewhat more flexible than the usual regularity condition of monotonicity. Some examples are given. As a by-product we get results on multidimensional regular variation of some independent interest.
