Parametric Distributional Flexibility and Conditional Variance Models with an Application to Hourly Exchange Rates /
This paper builds on the ARCH approach for modeling distributions with time-varying conditional variance by using the generalized Student t distribution. The distribution offers flexibility in modeling both leptokurtosis and asymmetry (characteristics seen in high-frequency financial time series dat...
