This will be important later on. Lastly, if the theory seems to make sense and the econometric model was not refuted on the basis of the hypothesis test, we can go on to use the theory for policy recommendation. Each example illustrates how to load data, build econometric models, and compute estimates with R.. Third, the parameter estimates have a very slim chance of being on similar lines with the actual parameter values that are generated by the statistical data, even if the econometrician identifies the process as the source of the original data.

But the theory itself does not provide any numerical measure of the strength of the relationship between the two; that is, it does not tell by how much the quantity demanded will go up or down as a result of a certain change in the price of the commodity. 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. Theoretical econometrics relies heavily on the likes of mathematics, theoretical statistics, and numerical quantities to prove that the new procedures have the ability to draw correct inferences.
