Matrix Kummer-Pearson VII Relation and its Application in Affine Shape
  A case of the matrix Kummer relation of Herz (1955) based on the Pearson VII type matrix model is derived in this paper. As a consequence, the polynomial Pearson VII configuration density is obtained and this set the corresponding exact inference as a solvable aspect in shape theory.
