说明：  内附源数据、代码及word。代码包括：平稳性检验、协整检验、滞后阶数的确定、VAR 模型的拟合、脉冲响应分析、VAR 模型的预测(Stationarity test, co integration test, determination of lag order, VAR model fitting, impulse response analysis, VAR model prediction)

可以用黄金分割和斐波那契算法实现优化,只要改变相应的参数就可以用了(You can use the golden section and the Fibonacci algorithm to optimize, just change the corresponding parameters.)

复杂网络聚类系数的matlab编程代码,将复杂网络存储为矩阵,再对其matLab编程,可得到度分布图(The MATLAB programming code of clustering coefficient of complex network is used to store complex network as matrix, and then matLab programming is used to get the degree distribution graph.)

多重分形去趋势波动分析法，用于不同时间序列的重分形交叉相关性分析。(Multifractal detrended fluctuation analysis)

CHKS光滑孪生支持向量机程序, 采用CHKS光滑函数逼近无约束孪生支持向量机的不可微部分，得到一类光滑的孪生支持向量机。(CHKS smooth twin support vector machine program)

牛顿插值法,选择插值节点文件,有点小麻烦()

人工智能中,经典的基于小波变换的图像处理和图像去噪的解决办法,可下载后观摩使用(In artificial intelligence, the classical image processing and image denoising based on wavelet transform can be downloaded and used)

分而治之方法与软件设计的模块化方法非常相似,为了解决一个大的问题,可以： 1) 把它分成两个或多个更小的问题； 2) 分别(The divide-and-conquer approach is very similar to the modular approach to software design. To solve a big problem, you can: 1) divide it into two or more smaller problems; 2))

一个很实用的采用Neville算法的拉格朗日插值程序,(A very practical Lagrange interpolation program using Neville algorithm,)

说明：  利用python进行数据分析，英文书籍，从pandas库的数据分析工具开始利用高性能工具对数据进行加载、清理、转换、合并以及重塑；利用matpIotlib创建散点图以及静态或交互式的可视化结果；利用pandas的groupby功能对数据集进行切片、切块和汇总操作；处理各种各样的时间序列数据。(Starting from the data analysis tools of pandas database, high performance tools are used to load, clean, transform, merge and remodel data; scatter plots and static or interactive visualization results are created by matpIotlib; data sets are sliced, sliced and aggregated by pandas group by function; and various operations are processed. Time series data.)
