1. Implicit Linear Inequality Edits Generation and Error Localization in the SPEER Edit System Maria Garcia U.S. Census Bureau UNECE Work Session on Statistical Data Editing May 16-18, 2005, Ottawa, Canada

2. SPEER Editing System  Fellegi-Holt system for continuous data under ratio and balance edits  All implied ratio edits are available

3. New SPEER System  Pre-processing program for implied edit generation  Optimality of ratio edits bounds  All SPEER modules rewritten  Simplified error localization  Calculation of imputation intervals

4. Number of Times Field in Balance Edits is Marked for Deletion ASM Fields

5. Remarks  Maintains SPEER exceptional speed  Better job of error localization  SPEER’97 heuristics not needed  Computer time (8 hours to generate linear inequality edits)
