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
Based on the information given, Martha is incorrect. Sam's quantity demand has decreased.
<h3>
What is demand?</h3>
Demand means the quantity of a good and services that consumers are willing and able to buy at various prices during a given period of time
In this case, Martha is incorrect. This is because Sam's quantity demanded has decreased, and his demand has not changed.

To combat this stereotyping the HR director has decided to<u> "adopt more transparent practices".</u>
Nowadays, pay transparency is an interesting issue among HR and compensation experts. Pay transparency doesn't need to be a win or bust approach where everybody knows every other person's compensation. Or maybe, we trust transparency is a range. It's how much an association will examine its general pay rehearses. Pay transparency is significantly something other than the dollar sum a business pays every worker. It's additionally being more open about how pay was resolved and giving a clarification of the organization's compensation grades.
I believe I excel at geological field work like mapping and showing the distribution of the rocks and features such as faults and explaining the landforms by their geological basis and also how geological structures can cause stability problems in open pit mines.

cost that is incurred due to damage to your car. It does not include the cost
for the other car. Therefore you will have to pay the total of $1,100</span>
