Secondly, the statistical model required to quantify the economic theory is defined. Intuition is as important as facts. For example, the econometrician might discover that the variance of the data (how much individual values in a series differ from the overall average) is always rotating and is never fixed over time. [1] Commonly distinguished differing approaches that have been identified and studied include: the Cowles Commission approach [2] the vector autoregression approach [3] This vignette reproduces examples from various chapters of Introductory Econometrics: A Modern Approach, 7e by Jeffrey M.
