Wishart and Pseudo-Wishart Distributions and Some Applications to Shape Theory, II
In this pap er, we determine the densit y of a singular elliptically con toured matrix. From this, the study of Wishart and Pseudo- Wishart distributions, whether cen tral or non-cen tral, whether singular or non-singular, is extended to the case of elliptical mo dels. Some applications of these res...

| Sumario: | In this pap er, we determine the densit y of a singular elliptically con toured matrix. From this, the study of Wishart and Pseudo- Wishart distributions, whether cen tral or non-cen tral, whether singular or non-singular, is extended to the case of elliptical mo dels. Some applications of these results are studied in the con text of shap e theory . Particular atten tion is paid to singular size- and-shap e and size-and-shap e cone densities. |
