We investigate the class of splitting distributions as composition a singular multivariate distribution and univariate distribution. It will be shown that most common parametric count (multinomial, negative multinomial, hypergeometric, …) can written with separate parameters for both components, thus facilitating their interpretation, inference, study probabilistic characteristics extensions to...

This paper is concerned with portfolio selection for an investor power utility in multiasset financial markets a rough stochastic environment. We investigate Merton’s problem different multivariate Volterra models, covering the Heston model. First we consider class of affine models introduced [E. Abi Jaber, E. Miller, and H. Pham, SIAM J. Financial Math.., 12 (2021), pp. 369–409]. Based on clas...
