Revealing the arcane: an introduction to the art of stochastic volatility models

Author

  • Tsyplakov, Alexander
Abstract
This essay is aimed to provide a straightforward and sufficiently accessible demonstration of some known procedures for stochastic volatility model. It reviews the important related concepts, gives informal derivations of the methods and can be useful as a cookbook for a novice. The exposition is confined to classical (non-Bayesian) framework and discrete-time formulations.
