  4. The Memobust project • Motivation: • European Statistical System (ESS) • Identification of best practices • Development of common methodology and guidelines supporting the production of business statistics • Integration of existing data sources

  5. The Memobust project • Operational objective: produce a handbook on methodology for the production of business statistics • Intended as an update of an existing handbook (1998) • Special focus on ‘new’ developments: • design of statistical processes • data collection • estimation • data integration • Comply with GSBPM • Sustainable → not a traditional handbook

  6. The handbook – scope • The handbook is about • methods that are currently used (or could be used) to produce business statistics within the ESS • some related aspects (e.g., process design, quality) • The handbook is not about • laws, regulations, etc. • official definitions of concepts → for this, see the Manual on European Business Statistics produced by FRIBS

  7. The handbook – intended readership • Persons working in the area of business statistics • survey managers • process designers • statisticians • methodologists • (users)

  8. The handbook – form and appearance • Appearance: • interconnected set of separate documents: modules • available as PDF files on the internet: http://www.cros-portal.eu/content/handbook-methodology-modern-business-statistics • Modules arranged into topics • 104 modules (+ introduction), 22 topics • Examples of topics: • Statistical Data Editing • Imputation • Glossary • 695 terms with 764 definitions

  9. The handbook – form and appearance • Two types of modules in the handbook: • Themes • general, broad readership • Methods • specific, more technical • Both types of modules have a fixed format (template)

  10. The handbook – possible uses • Source of knowledge / aid in designing and running business statistics • Information for users of business statistics • Material for courses on methodology • Starting point for tool development • Facilitate the discourse on statistical methods and harmonisation at the European level

  15. Editing and Imputation • Aim of the handbook: summarise existing knowledge, provide references for more details • Key references for Editing and Imputation: • EDIMBUS Manual (2007) • Handbook by De Waal, Pannekoek & Scholtus (2011) • UNECE Glossary of Terms on SDE (2000) • UNECE Work Sessions on SDE

  16. Concluding remarks • Project finished, handbook supposed to live on • Possible future developments: • Update existing topics/modules • Add new topics/modules • Transform to a different environment (e.g., wiki) • Required: • Active group of moderators and contributors • Perhaps UNECE Work Sessions could contribute? • Some form of financial support • “Centre of competence”? • Series of small dedicated projects?
