Presentation Transcript

  1. New and Emerging Methods Possible discussion points

  2. Automatic editing • Which errors are more important? • random errors? • systematic errors? • Do we need new methodology for detecting random errors? • based on edit rules? • based on statistical outlier detection? • What are the experiences with respect to detecting and correcting systematic errors at other agencies? • What kinds of systematic errors can we distinguish?

  3. Imputation • Is imputation under edit restrictions an important new topic? • Is imputation preserving known totals an important new topic? • Is multiple imputation the way of the future? • to smooth variability of single imputations? • to estimate (co)variances?

  4. Detection of influential errors/selective editing • In this session only one paper on selective editing • Is selective editing no longer “new and emerging”? • Are we near the end of the theoretical development of selective editing? • Should selective editing be based on complicated methods or do simple methods suffice?

  5. Impact of editing • Should we focus more on measuring the impact of (changing) the edit strategy? • What are the experiences at other agencies in this respect? • Can we improve on the Snowdon-X approach?

  6. Data • Is the focus shifting to periodic data/time series? • Is the focus shifting to longitudinal data?

  7. Software development • How should we develop software? • Open source • Commercial of the shelf • Find commercial vendor to develop software for us • Develop software together in international projects • Each agency develops its own software

  8. Edit and imputation • Is error localization more important than imputation? • Is imputation more important than error localization?
