Curvilinear regression models are often used in forecasting when ________.
A)dummy variables need to be used
B)the number of independent variables is high
C)the independent variable is time
D)the error term is approximately equal to zero

Question

Quizplus · Accepted Answer

Curvilinear regression models are commonly used in forecasting when the independent variable is time. This is because time is often nonlinear and requires a curvilinear model to accurately capture its impact on the dependent variable. Dummy variables, the number of independent variables, and the error term being close to zero are not factors dictating the use of curvilinear regression models.
