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: Option (B)
Explanation:
Here, in this case we can state that <em>job evaluation </em>is being exemplified. The Triano Brothers are using job evaluation, so as to have a systematic approach in order to determine value of a job in regards to the several jobs in their organization. The organization attempts to have a orderly comparison in between different jobs as to assess the relative value.
Answer:
It takes population size into account when measuring the value of goods and services.
Explanation:
GDP per capita is gross domestic product divided by the total population of a given economy. Thus, unlike the GDP-only measure, which measures the absolute value of domestic production, per capita GDP assesses how much a country's economy is growing per individual, that is, it shows the evolution of production per person.
Answer:
The correct answer is letter "E": cost of debt.
Explanation:
The cost of debt is the interest a company pays on its borrowings. It is expressed as a percentage rate. Also, the cost of debt can be calculated as a before-tax rate or an after-tax rate. Before interest is deductible for income taxes, the cost of debt is usually expressed as an after-tax rate.
