A regression model was applied to explain movements in the Canadian dollar's value over time. The coefficient for the inflation differential between the United States and Canada was − 0.2. The coefficient of the interest rate differential between the United States and Canada produced a coefficient of 0.8. Thus, the Canadian dollar depreciates when the inflation differential ____ and the interest rate differential ____.​

Respuesta :

The Canadian dollar depreciates when the inflation differential increases and the interest rate differential decreases.

Explanation:

Regression analyzes are a set of mathematical methods to determine the association of a dependent variable with one or more independent variables.

The equation has the form Y= a+ b X, where Y is the dependent variable (that's the variable that runs on the Y axis), X is the independent variable (i.e. it is plotted on the X axis), b is the line slope and a is the y-intercept.

Firstly, regression fits a model to predict.

Example: to form an equation of known house sales data (sale price, how many rooms, etc.) in order to forecast potential selling prices in the same region.
