Answer:
A
Explanation:
Discretionary fiscal policies are deliberate steps taken by the government to stimulate the economy in order to cause the economy to move to full employment and price stability more quickly than it might otherwise.
Discretionary fiscal policies can either be expansionary or contractionary
Expansionary fiscal policy is when the government increases the money supply in the economy either by increasing spending or cutting taxes.
If taxes are cut, disposable income increases and demand increases. this is an example of demand side
On the other hand, if a replacement project is undertaken, the demand for labour increases. this is an example of supply side
Contractionary fiscal policies is when the government reduces the money supply in the economy either by reducing spending or increasing taxes
Answer:
true: credit card history
Answer:
b). 72.458 %
a). 24, 213
Explanation:
1). The second option i.e. 72.458% correctly measures the variance percentage brought in the dependent variable(regressed the quantity demanded) by manipulating the independent variable(price elasticity). The first option is wrong as it shows R multiple which is rather the coefficient. The third and the last options are incorrect as they display the intercept employed to determine the quantity and the key error of calculating the standard deviation.
2). The predicted quantity demanded would be 24,213 if the price is fixed at $7.00.
It can be calculated using the formula;
Quantity demanded = Intercept + (Adjusted R squared * Price coefficient)
∵ Quantity Demanded = 56,400.50 + (7 X -4,598.2)
= 24,213
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
The firms may need to focus additional effort on retention strategies.
Retention strategies are means employed by firms to retain their customers both new and existing, over some specified period.
Where a company has high customer retention, it means customers would continue to patronize the company's products and not not defect to another product or business.
Customer retention process starts with the first point of contact in an organization and spread through the whole duration of the customer's relationship with the organization.
