Abstract
The linear regression method is important in natural science. This method is widely used in economics, data science, management, medicine, biology, sociology and so on. This statistic method helps people to find the relationship between inputs and outputs and classify massive data. In the following article, some basic theories, formulas and real problems with solutions will be mentioned. This essay firstly introduces some methods about linear regression, and then use the formula and basic theories to calculate and analyze the relationship between independent and dependent variables of some real massive data. Finally, it can be found that all of data have relationship and people can use these conclusions to predict or give a suitable strategy, so it is really useful for people to prepare solutions ahead of schedule. It is one of the most fundamental methods in dealing with data, because the model of linear regression is quite easy, and provide understandable mathematical formulas, then create some scientific results.
