Quizplus · Accepted Answer

In time series regression analysis, the independent variable represents time. The dependent variable can be any variable that is being studied over time, such as sales, stock prices, or temperature. The sign of the slope, b, can be positive or negative depending on the direction of the relationship between the dependent and independent variables. There is no general rule that the sign of the slope is usually negative or positive.
