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 $Var (\beta j )$ = σ^2 / $[TSS j (1 - R^2j)]$ ; 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

gtnhenbr [62]

Answer:

The answer is "increase; LRAS curve to the right".

Explanation:

The curve LRAS represents the flow between all the level of wages and economic GDP supplied because all prices are fully flexible, also with nominal salaries; its cost may change all along LRAS, however, the output cannot, as it represents the complete output of workers, that's why the several economists say that lower marginal rate consistently increases the motivation to work, shifting the LRAS curve to the left.

If Norman invested $100,000 for 3 years at 12%, how much interest on interest will he earn? (Do not round intermediate calculati

Scrat [10]

Answer:

$224.64

Explanation:

Norman invested $100,000, Interest rate 12%, Period 3 years

In compound account, the interest earned by the end of the year qualifies to earn interest. At the end of the period, the interest is added to the principal and earns interest as well.

The interest that Norman earned in the first year was added to the principal amount in the second year, meaning that interest earned some interest in the second and their year of investment. The same happened to the interest earned in the second year.

To calculate the interest earned by the interest, we take the amount after three years, minus the principal amount, minus the simple interest for the three years.

Interest on interest will be the Future value- principal amount- Simple interest.

The amount after three is the compounded value after three years.

compound amount formula FV= PV × (1+r)n

Future value of $100,00 @ 12% after 3 years will be

=5000 x (1+12/100) 3

=5000 x (1+0.12)3

=5000 X (1.12)3

=5000 x 1.404928

=7,024.64

The simple interest earned in the three years equal

Interest = principal x rate x duration

12/100 x 5000 x 3

=0.12 x 5000 x 3

=600 x 3

=$1800

Interest on interest will be :

=$7,024.64 - $5,000- $1,800

=$224.64
