Resumen
In this study, the Fuzzy Auto-Regressive Integrated Moving Average (FARIMA) Model has been used to predict gold prices, The main objective was to estimate the fractional parameters by using the fuzzy regression method of TANAKA. The prediction accuracy of the FARIMA method was measured and compared with the ARIMA method using mean square error (MSE) and mean square error (RMSE) for the time period from 2010 to 2018. Gold prices were also predicted using the two methods for the year 2019. The research concluded that FARIMA models are more efficient than ARIMA models in predicting gold prices.
