Tail Probabilities and Partial Moments for Quadratic Forms in Multivariate Generalized Hyperbolic Random Vectors

Broda, Simon A. - 2013

Countless test statistics can be written as quadratic forms in certain random vectors, or ratios thereof. Consequently, their distribution has received considerable attention in the literature. Except for a few special cases, no closed-form expression for the cdf exists, and one resorts to...

Optimisation of mixed assets portfolio using copula differential evolution: A behavioural approach

Ababio, Kofi A.; Mba, Jules Clement; Koumba, Ur - In: Cogent Economics & Finance 8 (2020) 1, pp. 1-27

Cumulative Prospect Theory (CPT) is rooted in behavioural psychology and has demonstrated to possess sufficient explanatory power for use in actual deci sion-making problems. In this study, two distinct asset classes (i.e. assets with extremely lower or higher CPT values) are classified and...
