Optimal Transport for Model Calibration [PDF]

SSRN Electronic Journal, 2021
We provide a survey of recent results on model calibration by Optimal Transport. We present the general framework and then discuss the calibration of local, and local-stochastic, volatility models to European options, the joint VIX/SPX calibration problem as well as calibration to some path-dependent options.

A simplified algorithm for leaky network analyzer calibration [PDF]

, 1995
A new algorithm for network analyzer calibration is presented. The error model includes leakage effects and can be applied to a general n-port NWA. The 2-port 16-term model becomes a special case of this new technique which is also hopefully suitable for

An Empirical Atmospheric Density Calibration Model Based on Long Short-Term Memory Neural Network

Atmosphere, 2021
The accuracy of the atmospheric mass density is one of the most important factors affecting the orbital precision of spacecraft at low Earth orbits (LEO). Although there are a number of empirical density models available to use in the orbit determination

Correction of bias in self-reported sitting time among office workers – a study based on compositional data analysis

Scandinavian Journal of Work, Environment & Health, 2020
OBJECTIVE: Emerging evidence suggests that excessive sitting has negative health effects. However, this evidence largely relies on research using self-reported sitting time, which is known to be biased.

On-Wafer Calibration Algorithm for Partially Leaky Multiport Vector Network Analyzers [PDF]

, 2005
A new solution for multiport vector network analyzer calibration is presented in this paper. The error model is divided in two separate leaky halves, each of them with crosstalk terms, but without the leakage between the two sides.
