How To Model Time Series Data With Linear Regression

Thus, after linear regression, it is always important to check the residual terms to ensure the Gauss-Marcov assumptions are not violated. Luckily, using the statsmodels library in Python, many statistical tests are automatically conducted during the linear regression. A simple print of the OLS linear regression summary table enables us to quickly evaluate the quality of the linear regression
