Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Canadian Journal of Statistics, EarlyView.Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Extremal Functions and Calderón's Reproducing Formula for the Laguerre-Bessel Two-Wavelet Transform [PDF]
Sahand Communications in Mathematical AnalysisThe main purpose of this paper is to study the wavelet transform associated with the Laguerre-Bessel transform and to provide an integral representation of the extremal function related to this transform. We then introduce the notion of a Laguerre-Bessel

Generalized series of Bessel functions
Journal of Computational and Applied Mathematics, 2002 Neumann series are series of the form \(\sum^\infty_{n=0} a_n J_{v+n} (z)\), where \(J_\mu\), is the Bessel function of the first kind and order \(\mu\). Neumann series may involve any type of Bessel functions. In this paper the authors prove several formulas that generalize known Neumann series.

A partial envelope approach for modelling multivariate spatial‐temporal data
Canadian Journal of Statistics, EarlyView.Abstract In the new era of big data, modelling multivariate spatial‐temporal data is a challenging task due to both the high dimensionality of the features and complex associations among the responses across different locations and time points.

Some expansion formulas for incomplete H- and H̅-functions involving Bessel functions
Advances in Difference Equations, 2020 In this paper, we assess an integral containing incomplete H-functions and utilize it to build up an expansion formula for the incomplete H-functions including the Bessel function.

Certain inequalities for the modified Bessel-type function
Journal of Inequalities and Applications, 2019 We establish some new inequalities for the modified Bessel-type function λν,σ(β)(x) $\lambda _{\nu ,\sigma }^{(\beta )} (x )$ studied by Glaeske et al. [in J. Comput. Appl. Math.
