There are many variables, e.g., the columns in a database, the questions in a survey, etc. If you have a regression model, you can find the relationships out and even predict the future values.
In this talk, I will introduce the correlation analysis, OLS (ordinary least squares), using R formula (an implementation in Python) to build model, covariance types, outliers, other common models, and the most important thing: how to build and interpret a model correctly.
Moreover, all the topics will be introduced with massive Python examples.
