<P>This book documents <a href="mailto:G@RCH" target="_blank" >G@RCH</A> 4.0, an OxMetrics application dedicated to the estima-<br>tion and forecast of univariate ARCH-type models (Engle, 1982), including some of<br>themostrecentcontributionsinthisfield. GARCH(Bollerslev,1986),EGARCH(Nel-<br>son, 1991), GJR (Glosten, Jagannathan, and Runkle, 1993), APARCH (Ding, Granger,<br>and Engle, 1993), IGARCH (Engle and Bollerslev, 1986), RiskMetrics (J.P.Morgan,<br>1996), FIGARCH (Baillie, Bollerslev, and Mikkelsen, 1996a and Chung, 1999), FIE-<br>GARCH (Bollerslev and Mikkelsen, 1996), FIAPARCH (Tse, 1998) and HYGARCH<br>(Davidson,2001)specificationsareavailablefortheconditionalvariance. Moreoveran<br>AR(FI)MA process can be specified in the conditional mean (see Baillie, Chung, and<br>`<br>Tieslau, 1996b, Tschernig, 1995, Teyssiere, 1997, or Lecourt, 2000, for further details<br>about ARFIMA models). All these models can be adapted to add an “ARCH-in-mean”<br>term inthe conditional mean as suggested by Engle, Lilien, and Robbins (1987).<br>Our software has been developed with the Ox matrix programming language of<br>1<br>Doornik (2001). <a href="mailto:G@RCH" target="_blank" >G@RCH</A> 4.0 should be compatible with a lot of platforms, including<br>Windows,Linux,UnixandSolariswhenitisusedincombinationwiththeOxConsole.<br>Furthermore, <a href="mailto:G@RCH" target="_blank" >G@RCH</A> 4.0 provides a menu-driven graphical interface for Microsoft<br>Windows users as well as a comprehensive HTML documentation. For most of the<br>specifications, it is generally very fast and one of its main characteristic is its ease of<br>use.<br>Overview of the <a href="mailto:G@RCH" target="_blank" >G@RCH</A> book<br>This book isstructured as follows:<br>* This chapter introduces the <a href="mailto:G@RCH" target="_blank" >G@RCH</A> software.<br>* Chapter 2 explains how to get started with <a href="mailto:G@RCH" target="_blank" >G@RCH</A>.<br>* Chapter3proposesanoverviewofthepackagefeaturesandapresentationofthe<br>simple ARCH model.
