    • Generalised Shape Theory Via Pseudo-Wishart Distribution 

      Díaz-García, José A.; Caro-Lopera, Francisco J. ( Springer on behalf of the Indian Statistical InstituteTronco común IngenieríasFacultad de Ciencias Básicas, 2013)
      The non isotropic noncentral elliptical shape distributions via pseudo-Wishart distribution are founded. This way, the classical shape theory is extended to non isotropic case and the normality assumption is replaced by ...
