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

Pollution control equipment for a pulverized coal cyclone furnace is expected to cost $190,000 two years from now and another $1

alexandr1967 [171]

Answer:

$212,882.75

Explanation:

Cost from 2 years now = $190,000

Cost from 9 years now = $120,000

Interest rate = 9% Quarterly

Present Worth = Cost from 2 years now*[1/(1+interest/m)^nm] * Cost from 2 years now*[1/(1+interest/m)^nm]

Present Worth = 190,000*[1/(1+0.09/4)^2*4] + 120,000*[1/(1+0.09/4)^9*4]

Present Worth = 190,000*[1/(1.0225)^8] + 120,000*[1/(1.0225)^36]

Present Worth = 190,000*[1/1.19483] + 120,000*[1/2.22782]

Present Worth = 190,000*0.83693915 + 120,000*0.4488693

Present Worth = 159018.4385 + 53864.316

Present Worth = 212882.7545

Present Worth = $212,882.75

Thus, the amount to invest to cover these cost is $212,882.75
