First we employ EMD method to decompose the crude oil prices in NYMEX, and obtain a series of intrinsic mode function (IMF), which are stationary and of strong periodicity, and a trend term.
首先利用EMD方法对NYMEX市场的原油期货价格进行分解，得到一系列平稳且具有较强周期性的本征模函数(IMF)和一个趋势项。
Trend term displacement is determined by the potential energy and constraint condition of the slope and is predicted by displacement polynomial function.
趋势项位移由边坡的势能和约束条件所决定，利用多项式位移函数进行拟合预测。
