Indirect Estimation of Long Memory Volatility Models

نویسنده

  • Nigel Wilkins
چکیده

An indirect estimator is proposed for two long memory volatility models; the fractionally integrated generalised autoregressive conditional heteroskedasticity (FIGARCH) model and the long memory stochastic volatility (LMSV) model. The small sample properties of the indirect estimator are compared to the small sample properties of conventional maximum likelihood estimators. It is found that the indirect estimator has the potential to perform favourably with respect to maximum likelihood for higher order parameterised FIGARCH and LMSV models.

Forecasting the Volatility of Nikkei 225 Futures ∗

For forecasting volatility of futures returns, the paper proposes an indirect method based on the relationship between futures and the underlying asset for the returns and time-varying volatility. For volatility forecasting, the paper considers the stochastic volatility model with asymmetry and long memory, using high frequency data for the underlying asset. Empirical results for Nikkei 225 fut...

Modeling long memory in stock market volatility

Inspired by the idea that regime switching may give rise to persistence that is observationally equivalent to a unit root, we derive a regime switching process that exhibits long memory. The feature of the process that generates long memory is a heavytailed duration distribution. Using this process for volatility, we obtain a regime switching stochastic volatility (RSSV) model that we "t to dai...

On the Log Periodogram Regression Estimator of the Memory Parameter in Long Memory Stochastic Volatility Models

We consider semiparametric estimation of the memory parameter in a long memory stochastic volatility model+ We study the estimator based on a log periodogram regression as originally proposed by Geweke and Porter-Hudak ~1983, Journal of Time Series Analysis 4, 221–238!+ Expressions for the asymptotic bias and variance of the estimator are obtained, and the asymptotic distribution is shown to be...
