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。

重言式的判别
资源描述
先来明确一下概念:一个逻辑表达式如果对于其变元的任一种取值均为真,则成为重言式;反之,如果对于其变元的任一种取值都为假,则称为矛盾式,然而,更多的情况下,既非重言式,也非矛盾式。 对于一个逻辑表达式,到底属于上面三种情况的哪一种,可以有很多种判断方法,如真值表法,直接证明法等等,这些你可以参考 请点击左侧文件开始预览 !预览只提供20%的代码片段,完整代码需下载后查看 加载中 侵权举报
