Description: 数据分析有极广泛的应用范围。典型的数据分析可能包含以下三个步：
1、探索性数据分析，当数据刚取得时，可能杂乱无章，看不出规律，通过作图、造表、用各种形式的方程拟合，计算某些特征量等手段探索规律性的可能形式，即往什么方向和用何种方式去寻找和揭示隐含在数据中的规律性。
2、模型选定分析，在探索性分析的基础上提出一类或几类可能的模型，然后通过进一步的分析从中挑选一定的模型。
3、推断分析，通常使用数理统计方法对所定模型或估计的可靠程度和精确程度作出推断。
数据分析过程实施
数据分析过程的主要活动由识别信息需求、收集数据、分析数据、评价并改进数据分析的有效性组成。

Description: 数据曲线移动量提取器
1.作图模块是用MFC自己编写的，调用MATLAB进行数据曲线的多项式拟合。
2.可以提取两根曲线间的偏移量：）
3.双击运行，如果提示“libeng.dll找不到”可能是机器上没装MATLAB
4.建议使用MATLAB6.5以上版本。
5.具体使用方法可以看程序的“帮助”项：） -Extraction of data curve mobile device 1. Graphing module is written in MFC itself, call MATLAB data polynomial curve fitting. 2. Can extract the offset between the two curves:) 3. Double-click to run, if you are prompted " libeng.dll not found" may be installed on the machine without MATLAB 4. Recommended MATLAB6.5 above. 5. Specific programs can be seen to use the " Help" item:)
