Python for Data Analysis

包含了01背包和非01背包两个程序！是我一次作业完成的,可以参考一下！()

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.)

本问题是计算最长有序子序列的一个动态规划算法,效率为31MS()

判断链表中是否有循环 有的话,按序打印一次(To determine if there is a loop in the list, print it in sequence)

说明：  boxcox函数的python实现，引用该函数可将偏态分布调整为正态分布(Python implementation of box Cox function)

GWR能够实现地理加权回归计算，里面有GWR4操作说明，虽然是英文，但有图片介绍，很容易理解，是GWR模型入门的好工具，适合经济学、数据挖掘等人员使用(GWR can realize geographically weighted regression calculation, including GWR4 operation instructions. Although it is in English, it has pictures to introduce, and is easy to understand. It is a good tool for GWR model entry. It is suitable for personnel such as economics and data mining.)

在linux 下C语言实现最近邻聚类算法，工程已经使用(near K neighbor cluster)

说明：  从数据库获取车辆在一段时间内的所有行驶记录的相关数据，确定所需数据为GPS经纬度坐标和驾驶时长等，QB模型采用MDF的思想,其基本思想为:通过平均直接翻转距离函数定义两条轨迹之间的距离，两条轨迹需要具有相同的经纬度点数，具有相同点数的轨迹最大的优点是对轨迹距离成对计算，且相同轨迹之间具有更高的分辨率，对于轨迹聚类的结果有一定的优化。(Retrieved from the database cars all over a period of time, record the related data, determine the required data for the GPS latitude and longitude coordinates, and the driving time, QB model by adopting the idea of MDF, its basic idea is: flip directly by the average distance function definition of the distance between two trajectories, two tracks will have the same latitude and longitude points, and has the biggest advantages of the same points of trajectory track distance calculation in pairs, and has higher resolution, between the same trajectory for trajectory clustering results have certain optimization.)

本书精心策划了三个虚拟项目，将数据科学家必需的专业技能融合其中，教会读者如何将数据存储到计算机内存中，如何在必要的时候转换内存中的数据值，如何用R编写自己的程序并将其用于数据分析和模拟运行。读者将跟随世界一流的RStudio培训师掌握宝贵的编程技能，并借助这些技能成为优秀的数据科学家。(Introduction to R Language)

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,)
