1. A non-transitory computer readable medium bearing instructions that, when executed, cause one or more computers to:
- identify;
retail data associated with a first entity, the retail data including data from a first data source and a second data source, the retail data further including product identifiers;
retail data associated with a second entity, the retail data including product identifiers, the retail data including data from a third data source; and
a plurality of factor calculations;
retrieve, based on the product identifiers, a plurality of overlapping attribute segments to use for comparing the data from the first and second data sources;
compare the plurality of the overlapping attribute segments;
calculate a plurality of factors for each of the overlapping attribute segments, each factor representing a bias present in the second data source, anduse the factors to adjust the values in the retail data from the third data source, thereby reduce bias present in the third source.

Abstract
The present invention provides a method for updating data sources. The method may include identifying a plurality of data sources, identifying a plurality of overlapping attribute segments to use for comparing the data sources, calculating a factor as a function of each of the plurality of overlapping attribute segments, and using the factors to update a first group of values in the second data source to reduce bias. Further, at least a first data source is more accurate than a second data source.
