Answer:
d. It is best measured using the statistic variance inflation factor (VIF).
Explanation:
Multicollinearity is an important issue in multiple regression model, having many independent/ explanatory variables. Multicollinearity is the situation in which two or more independent variables are highly correlated. It is problematic because it increases the standard error of independent variable coefficient & undermines its statistical significance
Variance Inflation Factor [VIF] is a check & corrective measure of multicollinearity.
- VIF as a multicollinearity check : It quantifies the correlation between one explanatory variable with other explanatory variables.VIF = 1 implies there is no multicollinearity (correlation between independent variables); VIF upto 5 implies there is moderate multicollinearity (correlation between independent variables). VIF > 5 implies high multicollinearity (correlation between independent variables)
- VIF as a multicollinearity correction : Calculating
= σ^2 / ![[TSS j (1 - R^2j)]](https://tex.z-dn.net/?f=%5BTSS%20j%20%281%20-%20R%5E2j%29%5D)
; where TSS = total sum of square of variable j , σ^2 = j variance, R^2 j = R^2 from regressing all other independent variable on variable j
the price of summer cabins. as summer approaches, the equilibrium price of rental cabins increases, and the equilibrium quantity of cabins rented increases increase in demand.
When the price falls below the equilibrium price, the quantity demanded exceeds the quantity supplied, creating an excess demand (short supply) for the product. In other words, consumers want to buy more than producers are willing to sell. This mismatch between supply and demand drives up prices.
Price movements cause equilibrium movement along the supply curve. Such a movement is called a change in supply. Like changes in demand, changes in supply do not shift the supply curve. By definition, it is moved along the supply curve.
