Abstract

A hybrid model has been considered an effective way to improve the forecast accuracy. This paper proposes the hybrid model of the linear seasonal autoregressive moving average (SARIMA) and the non-linear generalized autoregressive conditional heteroscedasticity (GARCH) in modeling and forecasting the Indian gold price. The goodness of fit of the model is measured using Akaike information criteria (AIC), while the forecasting performance is assessed using root mean square error (RMSE), mean absolute Error (MAE) and mean absolute percentage error (MAPE). The study concluded that SARIMAGARCH is a more appropriate model forecasting Indian gold price. The analysis is carried out by using the R (3.2.1)-software.
