This paper describes theory, computational algorithms, and software associated with the new SPEER edit system.
The SPEER edit system is based on the Fellegi-Holt model (JASA, 1976) of editing and is used on continuous data.
The key feature of the new SPEER system is that it automatically does ratio editing and a limited form of balancing
(assuring the items add to totals). The limited form of balancing appears to work in over 99% of the situations in
which balancing is needed and the associated computational algorithms are exceedingly fast. Other economic edit
systems are not able to do automatic balancing in a manner that assures records satisfy all edits.
