Quizplus · Accepted Answer

A linear trend model assumes that there is a consistent and gradual increase or decrease in the data over time. Therefore, if the time-series graph shows that sales data have grown gradually over the past 10 years, the sign on the regression slope coefficient in a linear trend model will be positive, indicating continued growth in future years.
