On Properties of the Hyperbolic Distribution

open access: yesMathematics
This paper is set to analytically describe properties of the hyperbolic distribution. This law, along with the variance-gamma distribution, is one of the most popular normal mean–variance mixtures from the point of view of various applications.

A new modified estimator of population variance in calibrated survey sampling

open access: yesScientific Reports
In survey statistics, estimating and reducing population variation is crucial. These variations can occur in any sampling design, including stratified random sampling, where stratum weights may increase the variance of estimators. Calibration techniques,

Gamma-gamma collider based on Compton back-scattering [PDF]

open access: yes, 1996
A {gamma}{gamma} collider would extend and complement the physics capability of a linear collider; e.g. it would be suitable for direct measurement of the partial decay width of a Higgs boson into two gamma quanta.

Option Pricing for the Variance Gamma Model: A New Perspective

open access: yes, 2023
The variance gamma model is a widely popular model for option pricing in both academia and industry. In this paper, we provide a new perspective for pricing European style options for the variance gamma model by deriving closed-form formulas combining ...
