WebApr 1, 1990 · Elliptically-Contoured Tensor-variate Distributions with Application to Improved Image Learning. Statistical analysis of tensor-valued data has largely used the tensor-variate normal (TVN) distribution that may be inadequate when data comes from distributions with heavier or lighter tails. We…. WebJan 30, 2013 · This paper focuses on a computationally tractable case—elliptically contoured stable laws. It is shown that one can compute densities, approximate cumulative probabilities for elliptical stable distributions in dimension \(d \le 100\). Maximum likelihood estimation for the parameters is feasible in low dimensions, and a pairwise estimation ... fed back information
Elliptically Contoured Models in Statistics and Portfolio Theory
WebIn this paper, Elliptically Contoured Distributions (ECDs) are used to model the statistical variability of HSI data. Non-homogeneous data sets can be modeled as a finite mixture of more than one ECD, with different means and parameters for each component. A larger family of distributions, the family of ECDs includes the multivariate normal ... WebJul 1, 2002 · A method utilized for this procedure is to embed the spherical distribution quantile transformation of each variable into an elliptically contoured distribution. The new class of distributions is then called meta-elliptical distributions. The corresponding analytic forms of the density, conditional distribution functions, and dependence ... WebTherefore, it seemed appropriate to collect the most important results on the theory of matrix variate elliptically contoured distributions available in the literature and organize them … declaration by witnesses meaning
