1. A computer-implemented method for imputing missing values for use in a fraud analysis predictive model, said method comprising:
- executing instructions on a computer system for receiving an input data set from a computer-readable data store wherein one or more values are missing with respect to one or more attributes of the input data set;
executing instructions on the computer system for determining a value for an attribute based upon a closed form equation representing the value to be used when encountering a missing value for the attribute;
wherein the closed form equation is based upon fraud-related tag information;
executing instructions on the computer system for using in the fraud analysis predictive model the determined value;
wherein the receiving an input data set, determining a value for an attribute, and using the determined value are performed on a data processor.

Abstract
Systems and methods for performing fraud detection. As an example, a system and method can be configured to contain a raw data repository for storing raw data related to financial transactions. A data store contains rules to indicate how many generations or to indicate a time period within which data items are to be stored in the raw data repository. Data items stored in the raw data repository are then accessed by a predictive model in order to perform fraud detection.

13. A computer-implemented system for imputing missing values for use in a fraud analysis predictive model, comprising:
-
a computer-readable data store to store an input data set wherein one or more values are missing with respect to one or more attributes of the input data set; value determination software instructions on a computer-readable medium to determine a value for an attribute based upon a closed form equation representing the value to be used when encountering a missing value for the attribute; wherein the closed form equation is based upon fraud-related tag information; wherein the determined value is for use in the fraud analysis predictive model.
