Indirect Inference: Which Moments to Match? [PDF]

open access: yesEconometrics, 2019
The standard approach to indirect inference estimation considers that the auxiliary parameters, which carry the identifying information about the structural parameters of interest, are obtained from some recently identified vector of estimating equations.

On Moment Matching for Stochastic Systems [PDF]

open access: yesIEEE Transactions on Automatic Control, 2022
In this paper we study the problem of model reduction by moment matching for stochastic systems. We characterize the mathematical object which generalizes the notion of moment to stochastic differential equations and we find a class of models which achieve moment matching.

Implementation of variance reduction techniques applied to the pricing of investment certificates [PDF]

open access: yesRisk Management Magazine, 2023
Certificates are structured financial instruments that aim to provide investors with investment solutions tailored to their needs. Certificates can be modeled using a bond component and a derivative component, typically an options strategy.

IMPLEMENTATION OF MONTE CARLO MOMENT MATCHING METHOD FOR PRICING LOOKBACK FLOATING STRIKE OPTION

open access: yesBarekeng, 2022
Monte Carlo method was a numerical method that was popular in finance. This method had disadvantages at convergences, so the moment matching was used to improve the efficiency from Monte Carlo method.

An Approximate Closed Formula for European Mortgage Options

open access: yesTrends in Computational and Applied Mathematics, 2023
The aim of this paper is to investigate the use of close formula approximation for pricing European mortgage options. Under the assumption of logistic duration and normal mortgage rates the underlying price at the option expiry is approximated by ...

Moment Evolution Equations and Moment Matching for Stochastic Image EPDiff [PDF]

open access: yesJournal of Mathematical Imaging and Vision, 2022
Models of stochastic image deformation allow study of time-continuous stochastic effects transforming images by deforming the image domain. Applications include longitudinal medical image analysis with both population trends and random subject specific variation.

Optimal H2 Moment Matching-Based Model Reduction for Linear Systems through (Non)convex Optimization

open access: yesMathematics, 2022
In this paper, we compute a (local) optimal reduced order model that matches a prescribed set of moments of a stable linear time-invariant system of high dimension. We fix the interpolation points and parametrize the models achieving moment-matching in a

Recalibration of LBM Populations for Construction of Grid Refinement with No Interpolation

open access: yesFluids, 2023
Grid refinement is used to reduce computing costs while maintaining the precision of fluid simulation. In the lattice Boltzmann method (LBM), grid refinement often uses interpolated values.
