Economies of Scale
Formulas
Y = β0 + β1X1 + β2X2 + ε
β1 = (Σ(YX1) - Σ(Y)Σ(X1)/n) / (Σ(X1^2) - (Σ(X1))^2 / n)
β2 = (Σ(YX2) - Σ(Y)Σ(X2)/n) / (Σ(X2^2) - (Σ(X2))^2 / n)
R^2 = 1 - (SS_res / SS_tot)
Theorems
Gauss-Markov Theorem
Ordinary Least Squares (OLS)
Suitable Grade Level
Undergraduate Level (Economics, Business Statistics)
