Asymptotic Analysis for Spectral Risk Measures Parameterized by Confidence Level [PDF]
Journal of Mathematical Finance, Vol.8, No.1, pp.197-226 (2018), 2017 We study the asymptotic behavior of the difference $\Delta \rho ^{X, Y}_\alpha := \rho _\alpha (X + Y) - \rho _\alpha (X)$ as $\alpha \rightarrow 1$, where $\rho_\alpha $ is a risk measure equipped with a confidence level parameter $0 < \alpha < 1$, and where $X$ and $Y$ are non-negative random variables whose tail probability functions are regularly ...

Information geometry and $α$-parallel prior of the beta-logistic distribution [PDF]
Communications in Statistics: Theory and Methods, 2024, 2023 The hyperbolic secant distribution has several generalizations with applications in finance. In this study, we explore the dual geometric structure of one such generalization, namely the beta-logistic distribution. Recent findings also interpret Bernoulli and Euler polynomials as moments of specific random variables, treating them as special cases ...
