Answer: D. Why the customer needs 5,000 extra flyers
Explanation:
The important factors that Sara will consider to know whether her company can accommodate the request are:
• Whether her company has enough paper on hand
• Whether her company can print the additional flyers without negatively affecting the other projects
• Whether there is enough time to print the additional flyers by tomorrow.
These factors above are important as they'll determine if she can accept the request or not. For example, in a situation where there's no enough paper, then the request should not be accepted.
The least important factor for Sara to consider will be "Why the customer needs 5,000 extra flyers". This is not of concern to Sara and shouldn't bother her.
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:
Limited liability company
Explanation:
In simple words, A limited liability corporation (LLC) is a type of private company structure. It's among the most frequent legal structures for forming a company. In a comprehensive partnerships all members are accountable for the firm and have unlimited accountability for its obligations.
Thus the limited liability structure is most suitable for the two.
