Application of SARIMA Model in Cucumber Price Forecast
Abstract:
The price of vegetables is difficult to predict. In order to find an effective method, this paper fully considers the seasonal variations, and uses the seasonal auto regressive integrated moving average model (SARIMA) to forecast the cucumber price. The experimental results indicate that the SARIMA(1,0,1)(1,1,1)12 fits the cucumber market prices exactly in the previous months. Its average fitting error is 17%. The forecast data of twelve months in 2011 is in line with the actual trend. Its average error reaches 25%. The SARIMA model is feasible for short-term warning of vegetable price.
