Nonresponse Reduction

McCarthy, Jaki (NASS)

As for all survey statistics, non-response has the potential to reduce the quality of establishment survey estimates. Therefore, US Federal agencies employ multiple strategies before, during, and after scheduled data collection to minimize non-response. This lecture will give an overview of current practices employed by US Federal statistical agencies including members of the Interagency Group on Establishment Non-response. The rationale for the effectiveness of these practices and specific examples from member agencies will be provided. In addition, several examples of empirical evaluation of the effectiveness of these strategies will be also presented. This is intended to provide audience members with a full palette of practical strategies to reduce non-response throughout all phases of data collection.

Nonresponse Bias Analysis for Establishment Surveys - Guidance from the U.S. Office of Management and Budget

Harris-Kojetin, Brian (OMB)

National Statistical Institutes have been facing declining response rates and increased costs of data collection for many surveys. In recent years, there has been an increased attention on nonresponse bias rather than response rates. In the U.S., the Office of Management and Budget issued guidance stipulating that Federal agencies conduct nonresponse bias analyses if survey response rates fall below 80 percent. This lecture will provide an introduction to issues of survey nonresponse and an overview of techniques for examining potential nonresponse bias in establishment surveys. The use of different analysis techniques will be illustrated with examples used by U.S. agencies on their establishment surveys.

Nonresponse Bias Analysis for Business Surveys - A Perspective from the U.S. Census Bureau

Thompson, K. Jenny (Census)

Although nonresponse bias is only one component of total survey error, mitigating it often poses substantive challenges for business surveys. For these programs, the statistics of interest are generally totals or percentage change in totals, and biases in either direction could lead to erroneous conclusions about the state of the economy. Business populations are highly skewed, with a large proportion of the estimated totals originating from a small set of cases. Moreover, viable response data can be obtained from different units than sampled: for example, a company may provide data for more than one sampled unit. High quality administrative data may be available from alternative data sources. This lecture discusses these challenges in detail and provides a broad overview of techniques used to conduct nonresponse bias analysis with business data.

Adjusting for Unit Nonresponse in an Establishment Survey Under a Logistic Response Model

Kott, Phil (RTI)

Many establishment surveys have a measure of size known for all units in the frame. Often, it is more reasonable to assume unit nonresponse is a logistic function of the log of this size measure (and other covariates) rather than the measure itself. We contrast several methods of estimating a total under that assumption with a simulated respondent sample of hospital emergency departments. It turns out the most efficient of these methods uses instrumental-variable calibration where the size measure is a calibration variable while its log is an instrumental variable. We then turn to the problem of estimating a total when unit nonresponse is a function of the survey variable itself by letting the log of the survey variable be the instrumental variable. SUDAAN 11 is employed to compute all estimates and large-sample standard errors.

A New Journal for WSS Members
Journal of Survey Statistics and Methodology (JSSAM)

The American Association of Public Opinion Research (AAPOR) and the American Statistical Association (ASA) announce the launching of a new interdisciplinary journal, the Journal of Survey Statistics and Methodology (JSSAM).

The purpose of JSSAM is to publish cutting-edge articles on statistical and methodological issues for surveys and censuses. It also will publish empirical and theoretical papers as well as applied papers and review papers. The journal will feature three sections. The Survey Statistics section will include papers on sampling procedures, imputation, weighting, measures of uncertainty, small area estimation, new methods of analysis, and other statistical issues related to surveys. The Survey Methodology section will include papers presenting methodological research, such as methodological experiments, comparisons of modes of data collection, and new uses of paradata. The Applications section will include papers that report innovative applications of methods, provide guidance on some practical problem, or present significant new findings. The first issue is scheduled to be issued in July 2013 and the journal will be published quarterly thereafter.

The founding co-editors of the new journal are well-known researchers. Joseph Sedransk will be the editor for statistical papers, and Roger Tourangeau will be the editor for the methodological papers. Dr. Sedransk is Professor Emeritus of Statistics at Case Western Reserve University; he received his Ph.D. in Statistics from Harvard University. Dr. Sedransk has also taught at Iowa State, Wisconsin, SUNY-Buffalo, University at Albany, and Iowa. Dr. Tourangeau is a Vice President at Westat. His Ph.D. is from Yale University in Psychology. Before going to Westat, he headed the Joint Program in Survey Methodology at the University of Maryland for nearly 10 years; during this time, he was also a Research Professor in the University of Michigan's Survey Research Center.

Oxford University Press (OUP) will be the publisher of JSSAM. OUP already publishes Public Opinion Quarterly (POQ), AAPOR's highly regarded journal that recently celebrated its 75th anniversary. AAPOR anticipates that JSSAM eventually will gain the stature that POQ has rightly earned in providing cutting-edge scholarship for the survey and opinion research communities and that the two journals will complement each other.

More information is available at the journal's website (http://jssam.oxfordjournals.org). Prospective authors can submit manuscripts online at http://mc.manuscriptcentral.com/jssam.
