GEIS
GEIS (Generalized Edit and Imputation System) is a processing system that was developed at Statistics Canada to meet the requirements of the Canadian economic surveys. Its main features are:
1. an error localization function which uses a minimum change approach, and
2. an imputation function which performs deterministic imputation, donor imputation, and imputation by estimators.
A more complete description is available in the GEIS evaluation page, on this site.
GEIS has been replaced by Banff in 2002 (see Banff in the Glossary). GEIS is no longer available and is not supported anymore.
