A quadratic model for long-term trend would be appropriate to describe a new product that has experienced a rapid early growth rate followed by the leveling off that is inevitable for any product. A quadratic model would capture the initial rapid growth with an upward sloping curve, followed by a leveling off as the growth rate slows down. Autoregressive models are used to describe time-series data that show a dependence on previous values, and linear models would not capture the leveling off of growth.
