Title: Topic (i): Selective editing / macro editing


1
Topic (i) Selective editing / macro editing
  • Discussants
  • Orietta Luzi - Italian National Statistical
    Institute
  • Rudi Seljak - Statistical Office of Slovenia
  • Pedro Revilla - National Statistical Institute of
    Spain

2
Background
  • The adoption of selective editing / macro editing
    approaches can significantly improve the
    efficiency of the data editing process
  • This is especially true in the case of business
    surveys where usually a small amount of
    measurement errors have a decisive influence on
    the final results and therefore the appropriate
    usage of selective editing and macro editing
    techniques can significantly reduce the cost of
    the data editing process with no major impact on
    the quality of the final results
  • Developing tools implementing selective editing
    models/functions may validly support further
    harmonization and widening use of efficient
    editing strategies in NSIs

3
Topic contents
  • Practical implementation of local and global
    score functions
  • Integration of selective editing / macro editing
    techniques within the statistical process
  • Tools to support selective editing / macro
    editing, including visualization approaches
  • Validation of selective editing strategies,
    inference issues
  • Editing of unstructured data

4
Long Presentations
  • Italy - Use of administrative data for selective
    editing the case of business investments
  • Spain - Score Functions under the Optimization
    Approach
  • United Kingdom Maintenance of Selective
    Editing in ONS Business Surveys

5
Short Presentations
  • Sweden Experiences from Selective Data Editing
    at Statistics Sweden
  • France Selective Editing Techniques and
    Seasonal Adjustment of Short-Term Economic
    Indicators
  • France Using R-indicators to monitor household
    surveys and prioritize data collection an
    application to the 2010 Household Wealth survey
    in France
  • Japan An Assessment of Automatic Editing via
    the Contamination Model and Multiple Imputation
  • United States Text Analysis Tools for Editing
    and Verification
  • Sweden Adjusting for Remaining Measurement
    Errors after Selective Editing

6
Short Presentations
  • Sweden Adjusting for Remaining Measurement
    Errors after Selective Editing (T. Laitila, A.
    Norberg)
  • Model-based approach for bias correction of
    estimators due to the remaining errors in
    selective edited data sets, where the observed
    measurement errors in the edited units are
    related to their scores.
  • The estimated models are used to predict
    measurement errors in unedited units and their
    associated bias.
  • Experimental application to data of the sample
    survey on establishments and their salary
    payments to employees carried on at Statistics
    Sweden.

  • Topic (i) Selective editing / macro editing
  • Discussion

8
Overall summary
  • Session papers provide a wide-ranging overview of
    current research and development activities in
    the area of selective / macro editing carried out
    at various NSIs with the aim of enhancing the
    efficiency of survey editing strategies
  • Theoretical formalizations of the selective
    editing paradigm are proposed, in a situation
    where no accepted theory has been developed in
    this area yet demanding modelling problems come
    out from presentations
  • The need of a common theoretical evaluation
    framework for quality assessment of selectively
    edited data is an area requiring further
    research at also an international perspective
  • Issues related to the development and
    dissemination inside NSIs of generalized
    IT-tools for selective editing are discussed,
    with specific attention to those relating to
    applicability, maintenance and optimization of
    the implemented methods/models
  • New application contexts where selective / macro
    editing principles can contribute to most
    efficient statistical production processes are
    explored

9
Points for discussion
  • Integrating selective / macro editing in existing
    EI process
  • Advantages (increased efficiency, burden
    reduction,)
  • Costs (re-design of processes, models/parameters
    maintenance/update due to changes of
    populations/information contexts, )
  • Cultural issues (changes in attitude needed,
    importance of support by the survey staff,
    importance of constant training and education,)
  • Countries experiences
  • Papers from Italy, Japan, UK, Sweden (A. Norberg)

10
Points for discussion
  • Formalization of selective editing
  • Ad hoc methods VS theoretical frameworks
  • How to estimate the model parameters?
  • How do we apply the developed frameworks in
    practice?
  • Papers from Italy and Spain

UNECE Work session on SDE, Paris, 28-30 April 2014
Topic (i) Selective editing / macro editing
10
11
Points for discussion
  • Standard tools for selective editing
  • Advantages (costs savings, harmonization, easy to
    document and to update, )
  • Drawbacks (specificity against generalization,
    validity of models assumptions, black-box
    effect, .)
  • International co-operation, sharing solutions
  • SeleMix (papers from Italy, Japan), Selekt
    (papers from Sweden, UK)

12
Points for discussion
  • Selective and macro editing and administrative
    data
  • Potentials (use of admin data as auxiliary
    information for error modeling/error
    detection/error correction)
  • Direct use of admin data for estimation purposes
    feasibility, costs, role of selective / macro
    editing
  • Paper from Italy

13
Points for discussion
  • Assessing the validity of a selective / macro
    editing strategy
  • Which indicators, quality measures, evaluation
    approaches
  • Inference and quality assessment under
    selectively edited data
  • Countries experiences
  • Paper from Italy, Sweden (Laitila-Norberg)

14
Points for discussion
  • New, innovative approaches in selective / macro
    editing strategy
  • Editing of unstructured data by using text
    analyses tools
  • Using R-indicators for prioritization of
    follow-up
  • Countries experiences
  • Paper from United States , France (Merly-Alpa)
