Residue Sum Formula for Pricing Options under the Variance Gamma Model

open access: yesMathematics, 2021
We present and prove a triple sum series formula for the European call option price in a market model where the underlying asset price is driven by a Variance Gamma process.

Sand-Dust Image Enhancement Using Chromatic Variance Consistency and Gamma Correction-Based Dehazing

open access: yesSensors, 2022
In sand-dust environments, the low quality of images captured outdoors adversely affects many remote-based image processing and computer vision systems, because of severe color casts, low contrast, and poor visibility of sand-dust images.

Higher-order asymptotic corrections and their application to the Gamma Variance Model

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We present improved methods for calculating confidence intervals and p values in situations where standard asymptotic approaches fail due to small sample sizes.

Confidence interval estimation of the common mean of several gamma populations

open access: yesPLoS ONE, 2022
Gamma distributions are widely used in applied fields due to its flexibility of accommodating right-skewed data. Although inference methods for a single gamma mean have been well studied, research on the common mean of several gamma populations are ...

Efficient Option Pricing under Levy Processes, with CVA and FVA

open access: yesFrontiers in Applied Mathematics and Statistics, 2015
We generalize the Piterbarg (2010) model to include 1) bilateral default risk as in Burgard and Kjaer (2012), and 2) jumps in the dynamics of the underlying asset using general classes of L'evy processes of exponential type.

Bayesian Option Pricing Framework with Stochastic Volatility for FX Data

open access: yesRisks, 2016
The application of stochastic volatility (SV) models in the option pricing literature usually assumes that the market has sufficient option data to calibrate the model’s risk-neutral parameters.

Pricing Embedded Options Using Fast Fourier Transform to Compare Variance Gamma and Black-Scholes-Merton Model Efficiency [PDF]

open access: yesIranian Journal of Finance
Embedded options are virtually new instruments identical to options in many aspects except their non-tradable nature. Testing the efficiency of the Variance Gamma and Black-Scholes-Merton model on these instruments would provide a vision of transitioning
