Abstract:
During the last two decade, the memory phenomenon have received increasing popularity for modelling market behaviour for both the return and the volatility of financial assets. Based on discrete-sampled observations, this paper considers the statistic inference of all the unknown parameters in a special stochastic processes with the memory phenomenon, namely, mixed fractional stochastic volatility model. The usual asymptotic properties, including strong consistency and asymptotic normality, are established under the long-span asymptotics, when the sampling interval is fixed and the sample size increases as the time span increases. The extension, when the volatility process has measurement errors, is also discussed. Monte Carlo experiments are performed to demonstrate the feasibility and effectiveness of the proposed method.
