In order to come up with a hypothesis to explain the relationships, econometricians would look at existing economic theories. When we add 1,000 new manufacturing jobs we get . Step 5: Divide the sum of squares by n - 1 or N. Divide the sum of the squares by n - 1 (for a sample) or N (for a population). . It establishes a straightforward relationship between the independent and dependent variables. Nonparametric methods in nancial econometrics The eld of nancial econometrics is much wider than what I presented here. B. An area of economics where statistical and mathematical methods are used to analyze economic data.
