<p>A marketing modeling system may include a modeling engine to determine a time-varying marketing driver model to estimate marketing driver contributions to sales for marketing drivers, and determine a time-varying parameter and multiply the time varying parameter by an independent time-varying variable in the time-varying marketing driver model. A driver contribution estimation module in the system may apply the time varying marketing driver model to consecutive fine-grained time periods to determine estimated contributions to sales for each fine-grained time period and for each marketing driver. > CL WC/cm o~W LC c~C) 0< _) 0 0 _ C) -) N LUU cl _D-Da m o o mS SN</p> |
