Tests of Certain Types of Ignorable Nonresponse in Surveys Subject to Item Nonresponse or Attrition
نویسنده
چکیده
Analysts of cross-sectional or panel surveys often base inferences about relationships between variables on complete units, excluding units that are incomplete due to item nonresponse or attrition. This practice is justifiable if exclusion is ignorable in an appropriate sense. This paper characterizes certain types of ignorable exclusion in surveys subject to item nonresponse and develops tests based on these characterizations. These tests are applied to data from several National Election Study panels and evidence is found of violations of these characterizations. Characterizations and tests of certain types of ignorable attrition in standard panel surveys are also presented.

Estimating Variance of the Sample Mean in Two-phase Sampling with Unit Non-response Effect
In sample surveys, we always deal with two types of errors: Sampling error and non-sampling error. One of the most common non-sampling errors is nonresponse. This error happens when some sample units are not observed or viewed but they do not answer some of the questions. The complete prevention of this error is not possible, but it can be significantly reduced. The non-response causes bias and ...
متن کاملComparison of Item and Unit Nonresponse in Household Surveys
1. Introduction Survey quality is thought to be impacted by nonresponse, both item nonresponse and survey or unit nonresponse. The relationship between item nonresponse and unit nonresponse has been studied by Dixon (2002). Dahlhamer et al. (2003) also studied item nonresponse across several federal surveys. The current study examines the nature of item nonresponse and the relationship with sub...
متن کاملIs Earnings Nonresponse Ignorable?
Is Earnings Nonresponse Ignorable? Earnings nonresponse in the Current Population Survey is roughly 30% in the monthly surveys and 20% in the annual March survey. Even if nonresponse is random, severe bias attaches to wage equation coefficient estimates on attributes not matched in the earnings imputation hot deck. If nonresponse is ignorable, unbiased estimates can be achieved by omitting impu...

Earnings nonresponse in household surveys is widespread, yet there is limited evidence on whether and how nonresponse bias affects measured earnings. This paper examines the patterns and consequences of nonresponse using internal Current Population Survey individual records linked to administrative Social Security Administrative data on earnings for calendar years 2005-2010.
