The Gray GM(1.1) Prediction in Wheat Production of Shandong Province Based on the MATLAB

Abstract

MATLAB is a kind of software which has powerful computing capabilities. This paper used the MATLAB software to computing the gray GM(1.1) prediction model, and establish the gray GM(1.1) prediction model based on historical data of production of wheat in Shandong Province. Through residual test, the prediction model is suitable for wheat prediction. This paper predicted the planting area, yield and output of wheat in Shandong Province from 2013 to 2015, and calculated the error range.
