However, local stochastic volatility models based on lognormal stochastic volatility models are market models, and Bergomi provides estimates of the breakeven gammatheta levels that those models generate for the spot and implied volatilities of vanilla options, by deriving approximate formulas for the volatilities of volatilities, spotvolatility correlations, as well as for the skewstickiness ratio. Steven Heston formulated a model that not only considered a timedependent volatility, but also introduced a stochastic model for stochastic volatility.
