A Necessary And Sufficient Condition For The Strict Stationarity Of A Family Of Garch Processes


  • Meitz, Mika


We consider a family of GARCH(1,1) processes introduced in He and Teräsvirta (1999a). This family contains various popular GARCH models as special cases. A necessary and sufficient condition for the existence of a strictly stationary solution is given.
