Linear regression vs time series

NettetA common source of omitted variable bias in a time series regression is time, itself. If two variables are trending in the same (opposite) direction over time, they will appear related if time is omitted from the regression. This is true even when there is no substantive relationship between the two variables. Many examples here.,.

However, Granger and Newbold argued that linear regression was an incorrect approach for analyzing time series due to the possibility of producing a spurious correlation.

NettetNormally distributed errors: Classical Linear models assume the errors of regression, also known as the residuals, are normally distributed with mean zero.This condition is also difficult to meet in real life.
