The Heterogeneity of the Differential Equation

The heston model is based on a complex mixture of random variability that is linked to the current acid price. It estimates future asid prices based on an array of perometers, including drift and mean reversion rates. In practice, the parometers for the hest model are determined based on real time auption prices. And there's the promlers that you use in terms of how the acid price will evolve over time.
