The parametric estimation of stochastic differential equations (SDEs) has been the subject of intense studies already … mathematics for the dynamics of asset prices and their volatility. Calibrating it to real data would be very useful in many … practical scenarios. It is very challenging, however, since the volatility is not directly observable. In this paper, a complete …
