The situation in which economic correlations involve only two variables are very rare. Rather we have a situation where a dependent variable, Y, can depend on a whole series of factorial variables or regressions. For example, the demand for a commodity depends not only on price but also on the prices of substitutes or complementary goods, the general level of consumer prices and resources. Thus, in practice, there are normally correlations.
