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。

双曲线回归方程 HyperbolaRegress.cs 注意!该模型要求a与b的值要大于0!使用该模型时应注意验证这个限制条件。我在实现模型时未加入任何出错流程控制。X不能为0。 方程模型为 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b,a。 public override double forecast(double x) 预测函数,根据模型得到预测结果。 public override double computeR2()

There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.
