Description: 一、 一元三次回归方程 CubicMultinomialRegress.cs
方程模型为Y=a*X(3)+b*X(2)+c*X(1)+d
public override double[] buildFormula()
得到系数数组，存放顺序与模型系数相反，即该数组中系数的值依次是d,c,b,a。
以后所述所有模型的系数存放均与此相同（多元线性回归方程除外）。
public override double forecast(double x)
预测函数，根据模型得到预测结果
public override double computeR2()
计算相关系数（决定系数），系数越接近1，数据越满足该模型。

Description: 移动平均预测 ModifyShiftAverageRegress.cs
移动平均也可画趋势图，如下：
public double forecast(int interval)
移动平均认为数据是时间序列数据，该方法预测interval个时间间隔后的值
public override double[] getTrendArray()
得到趋势数组，该数组的数据直接在图形中展示出来就可以产生趋势线。
