CurveFitter 执行统计回归分析，以估计线性、多变量、多项式、指数函数和非线性函数的参数值。回归分析确定使函数最适合您提供观测数据的参数的值。此过程也称为曲线拟合。 在几秒钟内将数千个数据放入方程中： CurveFitter 使科学家、研究人员和工程师能够找到最复杂数据的理想模型，包括可能从未考虑过的方程。您可以构建方程集，该方程集可以包括适用于任何应用的线性和非线性模型的广泛数组。其最先进的数据拟合包括以下功能： *包含最多 9 个参数和 8 个变量的任何用户定义的方程。 *线性方程。 *非线性指数、对数和功率方程。 *38 位精密数学仿真器，用于正确拟合高阶多项式和理性。 以图形方式查看曲线拟合结果： 数据拟合后，CurveFitter 会根据标准误差的统计标准自动对拟合方程进行排序和绘制。在"查看曲线拟合"窗口中为所选拟合方程生成残差图和参数输出。 有了所有这些能力，它仍然易于使用： CurveFitter 充分利用 Windows 用户界面来简化操作的各个方面 -- 从数据导入到结果输出。从 txt 格式导入数据。数据进入编辑器后，创建自定义方程集，只需单击鼠标即可启动自动拟合过程。CurveFitter 非常直观、易于使用且学习非常简单。
