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.
