An application of padé approximation to volatility modeling

María Gil Fariña and Rosa Lorenzo Alegría

International Advances in Economic Research, 1999, vol. 5, issue 4, 446-465

Abstract: This paper studies the dynamic relationship between future volatility and implied and historical volatility using data from Alegría and Rodríguez [1997]. The methodological approach forms part of the theoretical research being carried out in numerical analysis and especially from the rational Padé approximation. This tool helps to characterize simple computational methods in order to study questions about dynamic modelization of doubly infinite series. Considering noncausal series, where the expectations provided by economic theory or empirical evidence are included in available sample data, leads to dynamic specifications suitable not only from the perspective of fitting available data, but also from their predictive performance when compared to traditionally used formulae based merely on data analysis.
