Objectifs
At the end of this module, the student should have understood and be able to explain (main concepts):
- The Brownian motion, as well as the Wiener integral and Itô's formula.
- The relationship between a stochastic differential equation and its Fokker-Planck equation.
- The formulation of a solution to a parabolic or elliptic PDE using a suitably chosen stochastic process.
- The maximum likelihood estimation of parameters in a stochastic differential equation.
The student should be able to:
- Perform stochastic calculus by applying Itô's formula.
- Implement numerical methods for solving a parabolic or elliptic equation using a probabilistic approach based on solutions of stochastic differential equations.
- Use Girsanov's theorem combined with the ergodicity results of Markov processes to estimate parameters via maximum likelihood in stochastic differential equations.
