China gold futures price prediction model-From the perspective of the gray prediction

摘要

Because of its multiple properties, the formation of the gold price mechanism is very complex. Grey prediction method is a scientific quantitative prediction, which is based on raw data processing; to establish gray model, discover the law of its development, and what's more, to predict the future of the system. As though the reason for Chinese gold futures prices may be complicated, the results could be absolute. In the process of establishing the prediction model, in order to reduce the randomness for future price, the author accumulated the data and used the gray prediction method, attempting to establish a form from the limited size of the Chinese gold futures price data sample. Consequently, the model fits well, and it is able to describe the sample data pointed on the continuous time, with good prediction results. Therefore, the model could serve as a guiding reference on the short-term changes of China gold futures price.
