INCREASING THE ACCURACY OF OPTION PRICING BY USING IMPLIED PARAMETERS RELATED TO HIGHER MOMENTS [PDF]

open access: yes
The inaccuracy of the Black-Scholes formula arises from two aspects: the formula is for European options while most real option contracts are American; the formula is based on the assumption that underlying asset prices follow a lognormal distribution ...

A Quantile-Conserving Ensemble Filter Based on Kernel-Density Estimation

open access: yesRemote Sensing
Ensemble Kalman filters are an efficient class of algorithms for large-scale ensemble data assimilation, but their performance is limited by their underlying Gaussian approximation.

Stability Analysis and Finite Difference Approximations for a Damped Wave Equation with Distributed Delay

open access: yesMathematics
This paper presents a fully implicit finite difference scheme for the numerical approximation of a wave equation featuring strong damping and a distributed delay term. The discretization employs second-order accurate approximations in both time and space.
