In this paper, we use the plug-in and Whittle methods that are based on spectral regression analysis to test for the long memory property in 12 Asian/dollar daily exchange rates. The results according to the plug-in method show that with the exception of Chinese renminbi all series may have long memory properties. The results based on the Whittle method, on(More)
Abstract Systems with a time-delayed feedback occur in various areas, for example in physics, climatology, physiology, and economy. In case of a nonlinear feedback, the systems can show complex behavior, like bifurcations, several types of oscillations, and chaotic solutions. We propose a new technique for the analysis of deterministic nonlinear(More)
