RT info:eu-repo/semantics/article T1 A computationally efficient method for obtaining smoothed volatilities in long-memory stochastic volatility models A1 Marmol, Francesc A1 Pérez Espartero, Ana A1 Reboredo Nogueira, Juan Carlos A2 Ediciones Universidad de Valladolid K1 Economía política K1 Economía de empresa AB We provide a computationally e±cient method, based on Harvey (1998) proposal, to estimate the underlying volatility of asset returns using the Long-Memory Stochastic Volatility (LMSV ) model. The performance of our procedure is illustrated with an application to three series of daily exhange rates returns. A comparison of long memory GARCH-type volatilities with our smoothed ones is also presented.
