Abstract

Sales activity of a product at sales outlets including sales outlets at which sales activity data is sampled and unsampled sales outlets is estimated by determining the distances between each of the sampled sales outlets and each of the unsampled sales outlets and correlating sales activity data from the sampled sales outlets according to the determined distances. The sales activity volume of the product at the plurality of sampled outlets and the estimated sales activity volume of the product at the unsampled outlets are combined to obtain an estimate of sales activity for all the sales outlets. Sales activity of products prescribed by a physician at both the sampled and unsampled outlets can be estimated by correlating sales activity data for the prescribing physician at the sampled outlets according to the distances between the sampled outlets and the unsampled outlets.

Claims

means for receiving distribution information from each of the plurality of sampled locations;

first processing means for generating a first plurality of signals each characterizing one of the plurality of sampled locations and the at least one other location and a second plurality of signals each corresponding to a distance between the at least one other location and one of the sampled locations in a prescribed neighborhood of the at least one other location;

means for partitioning the received distribution information from the sampled locations, the distance corresponding signals and the characterizing signals into sets, each set corresponding to a group of the plurality of distribution locations;

second processing means comprising a plurality of second processors and a network for exchanging information among said second processors,

each second processor being responsive to one of the sets of distribution information, distance corresponding signals, characterizing signals and the information from the information exchange network for forming a signal representing an estimate of the product distribution of one group of the plurality of distribution locations by combining the received distribution information, the distance corresponding signals and the characterizing signals.

2. A system according to claim 1, wherein the partitioning means comprises:

a store for storing the received distribution information, the distance corresponding signals and the characterizing signals from the first processing means;

means for dividing the stored distribution information, the distance corresponding signals and the characterizing signals from the first processing means into the sets; and

9. A system according to claim 8, wherein the product is a prescription medicine, each source is a prescription medicine prescriber, each of the sampled and unsampled locations is a pharmacy, the characterizing signal T_S represents a size of the sampled pharmacy S and the characterizing signal T_U represents a size of the unsampled pharmacy U.

10. A system according to claim 5, wherein the partitioning means comprises:

a store for storing the received distribution information and the characterizing signals from the first processing means;

means for dividing the stored distribution information and the characterizing signals into the sets; and

means for transferring the sets from the dividing means to the second processors.

11. Apparatus for estimating distribution of a product by a distributing authority at a plurality of first distribution locations at which distribution information of the distributing authority is sampled and second distribution locations, comprising:

means for receiving distribution information of the distribution authority from each first distribution location;

first processing means responsive to predetermined characteristics of each of the first and second distribution locations for Generating a plurality of signals each representative of a factor by which the second distribution locations affect distribution at each first distribution location and for generating a plurality of signals each representative of the distance between each second distribution location and each first distribution location in a prescribed neighborhood of the second distribution location;
