Abstract: We propose a two stage procedure for the estimation of the parameters of a fairly general, continuous-time stochastic volatility model. An important ingredient of the proposed method is the Cuchiero–Teichmann volatility estimator, which is based on Fourier transforms and provides a continuous-time estimate of the latent process. This estimate is then used to construct an approximate likelihood for the parameters of interest, whose restrictions are taken into account through prior distributions. The procedure is shown to be highly successful for constructing the posterior distribution of the parameters of a Heston model, while limited success is achieved when applied to the highly parametrized exponential-Ornstein–Uhlenbeck.
