We study variance functions of the Cauchy-Stielties kernel (CSK) families generated by compactly supported centered probability measures. We describe several operations that allow to construct additional variance functions from known ones. We also construct a class of examples which we believe exhausts all cubic variance functions, and provide other examples of polynomial variance functions.
