A Review of (Total) Survey Error Models William D. Kalsbeek Survey Research Unit University of North Carolina
Purpose To review the following for existing total survey error (TSE) models: • Composition and Structure • Presentation • Utility
Presentations of TSE Models • TSE Model (a Definition): * • A postulation to understand or predict, by theory or simulation, the properties or behavior of the survey process • Presentations of TSE: • Practical: • Process origins; plus statistical nature, impact, measurement and/or control of error • Theoretical: • A formulary (usually MSE-based) *Based on Kotz, et al. (1981-89).
Thesis TSE Models • Have organized our thinking on the statistical effects of error sources But • Translation of this understanding into practical improvement has been limited and largely marginalized to individual sources of error
Thesis For the Future: • Greater research emphasis on TSE components and application of TSE findings for a broader array of data systems? • Model re-direction needed?
Sources of Error * • Sampling • Frame • Measurement • Nonresponse (Unit/Item) * One might also view the underlying stochastic model responsible for the data array in model-based inference as a source of error
A Review of TSE Presentations • Tracking presentations for 2+ sources • Structural basis • Various decompositions of MSE • Grouping by number of sources and: • Type of presentation (practical/theoretical) • Source interrelationship (separate/integrated) • Question: • Which parts of the survey process have TSE models accommodated?
Sources of Error • Sampling • Frame • Measurement • Nonresponse (Unit/Item)

Two-Source Theoretical (Integrated): • Nonresponse Bias • Hansen and Hurwitz (1946) • Several extension to more complex sample designs • El-Badry (1956) • Rao (1968, 1973) • Rao and Hughes (1983)
Two-Source Theoretical (Integrated): • Measurement Error Model • Hansen, et al. (1951a, 1951b, 1961, and 1964) • Subsequent work by others at the Census Bureau • Forsman (1989) review
Two-Source Theoretical (Integrated): • Multiplicity Estimators: • Birnbaum and Sirken (1965) • Several subsequent papers by Sirken, et al.
Two-Source Theoretical (Integrated): • Model-Based Inference with Missing Data • Little (1995) • Little and Rubin (2002)
Three-Source Theoretical (Integrated): • Platek, et al. (1977, 1983) • Lessler (1983)
All-Source Practical (Separate): • Following Kish (1965) • Anderson, et al (1979) • Groves (1989) • Groves, et al. (2004) • Federal Committee on Statistical Methodology • FCSM (2001) • Kasprzyk & Giesbrecht (2003) • Other error profiles by Bailar and colleagues for Census statistics
All-Source Theoretical (Separate): • Lessler and Kalsbeek (1992) • Sarndahl, Swennsson, and Wretman (1992)
All-Source Theoretical (Integrated): • A general model appended to Lessler and Kalsbeek (1992)
Utility of Existing Models • Provides a theoretical basis in survey practice to: • Structure our thinking • Motivate preventive strategies • Suggest process quality indicators • Suggest measurement approaches • Catalog empirical findings
Limitations of Existing Models * • Compartments and smokestacks • Marginalized treatment of error sources • Plausibility and complexity • Inverse relationship between proximity to reality and complexity • Context and comparability • Breadth of model utility • Lack of Attention • Priorities and cost * Inspiration and insight from Platek and Sarndahl (2001)
Questions for the Future • More emphasis on studying and minimizing TSE? • For the major and minor leagues • Greater integration of TSE and practice? • Cataloging and lessons learned • New directions in TSE model structure? • All sources jointly TSE • Action-directed models TQM? • More process indicators
