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 /
; 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:
D. $10,000
Explanation:
The answer is D because as you earn $50,000 every year, and for the next year the tax rate is 20%, 20% of $50,000 is $10,000. Hope it helps!
Answer: The correct answer is "a. You may have to tell your accountant to conduct reconciliations to ensure that the rates in the system make sense when compared to actual rates.".
Explanation: Paul should surely recommend that your accountant verify the rates applied in the accounting system have reliability and are correctly related to the actual rates and if not, perform the necessary reconciliations.
