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。

这是一个简单的演示如何评价文本的数学表达式
This a simple demo of how to evaluate mathematical expressions in text
format, including provision for variables and functions. The code consists of
three simple classes: 1) Calc - which does the main calculations, 2) Stack -
which is used to push and pop intermediate operators and numbers and 3)
Symbol Table. The symbol table is a collection of calc symbols, a type structure
consisting of various elements, including the expression name, function name,
and the final value of the expression The evaluation procedure is done in three
steps: 1) simplify the expression by removing all the elements within () and
storing them in subexpressions within the symbol table. 2) Each of these sub
expressions are then converted to RPN format (Reverse polar notation) and
evaluated 3) Finally, the main expression is converted to RPN and evaluated-This is a simple demo of how to evaluate mathematical expressions in text
