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
Answer:
Total Revenue of Cocaine will increase.
Explanation:
Elasticity of demand is demand responsiveness to price change.
Price & Total Revenue have relationships as per Elasticity of Demand :
- Elastic Demand >1 : Change in quantity demanded > change in price ; Price & Total Revenue negatively related.
- Inelastic Demand < 1 : Change in quantity demanded < price change ; Price & Total Revenue positively related
Given : Demand for crack cocaine is inelastic. If government increases penalties on cocaine supply, number of dealers decrease.
Then , the supply of cocaine will fall. Supply Shortage will increase the price. However - because demand is inelastic , total revenue will increase as a result of price rise.
