ExcelVBA编程实现多元线性回归

作者: 柳誉鸣 | 来源:发表于2020-04-18 11:11 被阅读0次

    要想掌握编程技术，最好的办法就是动手做，跟我来吧！
    这是几个月以前我用Excel VBA进行的几个编程练习，涉及到字符串处理，计算，用户界面控制，以及基本的统计学知识。主要是3个案例，1是多元线性回归，人输入公式，要Excel自动读取并回归出权重值；2是蒙特卡洛模拟，给定几个指标的概率分布，让Excel自动测算任意次运行结果；3是美国城市距离测算，重点在搜索算法应用，以及VBA从网页爬取信息（但是爬虫还是Python方便啊真的哈哈）。

    不说废话，这篇文章讲第一个案例，Excel中怎么识别任意种回归公式？

    其实类似于操作Eviews时在控制行输入公式的做法。

    目标： 首先是这样的用户页面.png

    约定：A列x值，B列y值，VBA将根据位置读取数据；给出f1-f4四项，可以输入任意符合“与x相关的数学表达”规则的公式，例如图中给出了平方，分数，对数运算，加减更不在话下。

    编程重点：首先页面实现，打开开发工具创建即可，其次公式识别，字符串处理，最后权重回归，弹窗返回。同时要有拖动滑块选定任意行数据的功能。

    D到G列输出各项值并弹窗返回回归结果.png

    同时VBA应计算出这次回归的统计指标，例如R值，并且将回归曲线作图返回。R值在作图之前弹窗提示。
