Abstract:   (1696 Views)
Fuzzy time series prediction models have been expanding in recent decades. These models provide decent behavior for unambiguous and incomplete data that do not have a linear structure. This paper examines the fuzzy percentage change model and compared to Arima's model. The efficiency of the proposed model for forecasting OPEC crude oil was evaluated and it was shown that this model has a lower error rate for data with high volatility.
Keywords: Percent changes, time series, fuzzy, ARIMA model.
