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:
Change in Assets is $127,500
Explanation:
The accounting equation for a corporation is:
Assets = Liabilities + Stockholders' Equity
⇒ Liabilities = Assets - Stockholders' Equity
= $285,000 - $130,500
= $154,500
At the end of years,
- Liabilities amount = Liabilities in the beginning + Change in liabilities = $154,500+ $90,000 = $244,500
- Stockholder's equity amount = Stockholder's equity + Change in stockholder's equity = $130,500 + $37,500 = $168,000
The assets at the end of year = $168,000 + $244,500 = $412,500
Change in Assets = $412,500 - $285,000 = $127,500
Shorter answer:
Change in Assets = Change in Liabilities + Change in Stockholders' Equity
= $90,000 + $37,500 = $127,500
Answer:
C) A 25% increase in sales resulting in a 30% increase in net operating income.
Answer:
The Sammy and Monica’s medical expense deduction for regular income tax purposes is $17,750.
Explanation:
For the purpose of regular income tax, the deduction pertaining to medical expenses are available up to the extent it exceeds 10% of AGI.
Deduction available = excess expenses incurred - 7.5% of AGI
= ($16,000 + 4,000 + 2,500
+5,000) - 7.5%*130000
= 27500 - 9.750
= $17,750
Therefore, The Sammy and Monica’s medical expense deduction for regular income tax purposes is $17,750.
