A method for tuning a demand model in manner that is stable with respect to fluctuations in the sales history used for the tuning is provided. A market model is selected, which predicts how a subset of the parameters in the demand model depends upon information external to the sales history; this model may itself have a number of parameters. An effective figure-of-merit function is defined, consisting of a standard figure-of-merit function based upon the demand model and the sales history, plus a function that attains a minimum value when the parameters of the demand model are closest to the predictions of the market model. This effective figure-of-merit function is minimized with respect to the demand model and market model parameters. The resulting demand model parameters conform to the portions of the sales history data that show a strong trend, and conform to the external market information when the corresponding portions of the sales history data show noise.

A system and method for estimating scanner-like sales figures based on audit data. Audit data collected at retail locations is associated with multiple purchases. For each purchase, determine the date of purchase and the number of pieces purchased in relation to the purchased item. For each purchase date, a decay rate is determined that causes the number of units purchased to decrease when the next consecutive purchase date occurs. The decay rate is the estimated daily sales volume between two consecutive purchase dates. Causal data can also be collected at the retail point, which is considered valid during a causal audit. The total estimated sales that occurred during the causal audit period can be determined by summing the estimated daily sales for each purchase date during the causal audit period. During a causal audit, the relationship between causal data and total estimated sales can be determined. If a relationship between causal data and total estimated sales is determined, one or more marketing strategies can be developed using the determined relationship. By analyzing market strategies using one or more analytical market models, it is possible to determine whether these market strategies are viable. Any proven marketing strategy can be implemented in a retail environment. Later, updated audit data and causal data can be collected and analyzed in the manner described above in order to monitor the performance of one or more implemented marketing strategies.
