Terminal-Dependent Statistical Inference for the FBSDEs Models

الملخص EN

The original stochastic differential equations (OSDEs) and forward-backward stochastic differential equations (FBSDEs) are often used to model complex dynamic process that arise in financial, ecological, and many other areas.

The main difference between OSDEs and FBSDEs is that the latter is designed to depend on a terminal condition, which is a key factor in some financial and ecological circumstances.

It is interesting but challenging to estimate FBSDE parameters from noisy data and the terminal condition.

However, to the best of our knowledge, the terminal-dependent statistical inference for such a model has not been explored in the existing literature.

We proposed a nonparametric terminal control variables estimation method to address this problem.

The reason why we use the terminal control variables is that the newly proposed inference procedures inherit the terminal-dependent characteristic.

Through this new proposed method, the estimators of the functional coefficients of the FBSDEs model are obtained.

The asymptotic properties of the estimators are also discussed.

Simulation studies show that the proposed method gives satisfying estimates for the FBSDE parameters from noisy data and the terminal condition.

A simulation is performed to test the feasibility of our method.
