A general review of distribution functions reveals that the twoand three-point correlation functions familiar to galaxy studies may be identified with the total correlation functions relevant to the study of liquids. In this context a discussion is included of the Peebles-Groth three-point correlation function. A recently derived two-point correlation function in polynomial form is reviewed.Renormalization of this expression is found to bring it into very good agreement with the wellestablished r~form {where r is intergalaxy displacement and y is a constant).
