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()

对数回归方程 LogarithmRegress.cs 方程模型为 Y=a*LnX+b 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() 计算相关系数(决定系数),系数越接近1,数据越满足该模型。
