Systems and methods to summarize transaction data via cluster analysis and factor analysis. In one aspect, a method includes identifying at least one set of clusters based on a cluster analysis of transaction records to group entities, identifying a plurality of factors based on a factor analysis of the transaction records to reduce correlations in spending variables, classifying an entity according to the at least one set of clusters, and computing values of the factors based on the transaction records of the entity. |
