Abstract:
|
For historical data, sequences of transactions that are supposed to be consecutive may contain gaps. A hot-deck based method of imputation, combined with a degree of randomization, is proposed. It is common in sequences of financial transactions to periodically "pay off the balance" with a single payment, returning the balance to zero. This feature is incorporated into the imputation procedure. The imputation procedure has been developed for imputing gaps in sequences of transactions in financial accounts. The procedures will be illustrated on data that are fictitious but retain interesting features found in the real world data that the method was devised to address.
