In classical regression analysis, it is assumed a linear relationship between a dependent variable y and a predictor variable x. The standard regression model for n observations of y (denoted by y_i for i = 1, …,n) and x (denoted by x_i for i = 1,…,n) can be written as.

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. Non-correlated variables: Finally, the regression variables are assumed to be non-correlated with each other, and preferably independent of each other. Nettet19. jun. 2014 · An interrupted time series design is a powerful quasi-experimental approach for evaluating effects of interventions introduced at a specific point in time. To utilize the strength of this design, a modification to standard regression analysis, such as segmented regression, is required. In segmented regression analysis, the change in …
