초록
A class of asymmetric ARCH processes is proposed via binary randompower transformations. This class accommodates traditional nonlinear modelssuch as threshold ARCH (Rabemanjara and Zacoian (1993)) and Box-Coxtype ARCH models(Higgins and Bera (1992)). Stationarity condition of themodel is addressed. Iterative least squares(ILS) and pseudo maximum likelihood(PML) methods are discussed for estimating parameters and relatedalgorithms are presented. Illustrative analysis for Korea Stock Prices Index(KOSPI) data is conducted.
