Based on some other answers (such as Marginal Distribution of Uniform Vector on Sphere), I understand that the marginal of a uniform distribution on a hypersphere is a Beta distribution.

Is there a paper/textbook that proves this seemingly standard result that I could cite in my paper? Note that the link I shared does have the answer, but I'm looking for something that I can cite.
