Empirical model for forecasting exchange rate dynamics : the GO-GARCH approach
Isenah, Godknows M.; Olubusoye, Olusanya E. - In: CBN journal of applied statistics 7 (2016) 1, pp. 179-208
The study aimed at determining a set of superior generalized orthogonal-GARCH (GO-GARCH) models for forecasting time-varying conditional correlations and variances of five foreign exchange rates vis-à-vis the Nigerian Naira. Daily data covering the period 02/01/2009 to 19/03/2015 was used, and...
