Svi stochastic volatility inspired. The stochastic volatility inspired , SVI parameterization of the implied volatility surface was originally devised at Merrill Lynch in 1999
For a stochastic volatility model Some parametrisation of the volatility surface, such asSVI are based on the Heston model CEV model. 2 The parametric model is the SVI stochastic volatility inspired model published by Professor Jim Gatheral in 2004 and later inThe Volatility Surface.
