Abstract
Flexible models for the innovation process of GARCH models have been limited. Here, we show the flexibility of two recently proposed distribution due Zhu and Zhinde-Walsh(J Econom 148:86-99, 2009) and Zhu and Gabraith (J Econom 157:297-305, 2010) by means of GARCH modeling of five popular commodities. The five commodities considered are Cocoa bean, Brent crude oil, West Texas intermediate crude oil, Gold and Silver. For each commodity, one of tht two models due to Zhu and Zhinde-Walsh (2009) and Zhu and Galbraith (2010) is shown to perform better than those commonly known.
