Stationarity and moment structure for Box-Cox transformed threshold GARCH(1,1) processes
This article introduces threshold GARCH(1,1) processes to which Box-Cox transformations are applied. This class of processes includes nonlinear ARCH and GARCH models as special cases. The model accommodates asymmetries in conditional variances through a "threshold". The stationary solution is explicitly obtained and moment structures are investigated.
