Banff is a processing system that was developed at Statistics Canada to meet the requirements of the Canadian economic surveys. Banff replaces the previous system GEIS (see GEIS in the Glossary). Its main features are:
1. an outlier detection function for univariate detection
2. an error localization function which uses a minimum change approach, and
3. an imputation function which performs deterministic imputation, donor imputation, imputation by estimators and mass imputation.
A more complete description is available in the Banff evaluation page, on this site.
