When it comes to data mining, we tend to focus on algorithms during modeling while ignoring other steps. In real world data mining projects, other steps are the key to determining project success or failure. Guide to intelligent data analysis is the book recommended by the knime official website (http://tech.knime.org/

Since 2005, Python has been used more and more in the financial industry, thanks to increasingly sophisticated libraries (numpy and pandas) and a wealth of experienced programmers. Many organizations find that Python is not only a great fit for an interactive analysis environment, but also a very useful system for developing files, which takes much less time than Java or C + +.

. Because R2 >0.99, so this is a very obvious experimental model of linear characteristics, that is, the fitting line can be explained by more than 99.99%, covering the measured data, has a good general, can be used as a standard work curve for other unknown concentration solution measurement. To further use more metrics to describe this model, we use the "regression" tool in data
