We formulate a bivariate stochastic volatility jump-diffusion model with correlated jumps and volatilities. An MCMC … stock (PX index) returns. Four bivariate models with and without jumps and/or stochastic volatility are compared using the … deviance information criterion (DIC) confirming importance of incorporation of jumps and stochastic volatility into the model …

We investigate the performance of the Heston stochastic volatility model in describing the probability distribution of …

We develop a new efficient and analytically tractable method for estimation of parametric volatility models that is … empirical Laplace transform of the unobservable volatility. The estimation then is done by matching moments of the integrated …-day data into the Realized Laplace Transform of volatility, which is a model-free and jump-robust estimate of daily integrated …
