Generalised shape theory via pseudo-Wishart distribution
José A. Díaz-García, Francisco J. Caro-Lopera
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…
Shape theory via polar decomposition
Jose A. Diaz-Garcia, Francisco J. Caro-Lopera
This work proposes a new model in the context of statistical theory of shape, based on the polar decomposition. The non isotropic noncentral elliptical shape distributions via pola…
Shape Theory Via SV Decomposition II
Jose A. Diaz-Garcia, Francisco J. Caro-Lopera
The non isotropic and non central elliptical shape distributions via the Le and Kendall SVD decomposition approach are derived in this paper in the context of invariant polynomials…
Shape theory via SVD decomposition I
Jose A. Diaz-Garcia, Francisco J. Caro-Lopera
This work finds the non isotropic noncentral elliptical shape distributions via SVD decomposition in the context of zonal polynomials, avoiding the invariant polynomials and the op…
Shape Theory via QR decomposition
Jose A. Diaz-Garcia, Francisco J. Caro-Lopera
This work sets the non isotropic noncentral elliptical shape distributions via QR decomposition in the context of zonal polynomials, avoiding the invariant polynomials and the open…
