Unit- und Item-Nonresponse

2014
Wenn Stichproben nach dem Zufallsprinzip (Hader/Hader, Kapitel 18 in diesem Band) generiert werden, kommt es regelmasig vor, dass in die Stichprobe gezogene Personen von vornherein nicht teilnehmen, den Fragebogen nur teilweise beantworten oder aus unterschiedlichen Grunden nicht erreicht werden konnen (Engel et al. 2004: 43).

Personality as a Predictor of Unit Nonresponse in an Internet Panel

Sociological Methods & Research, 2018
Unit nonresponse in panel data sets is often a source of bias. Why certain individuals attrite from longitudinal studies and how to minimize this phenomenon have been examined by researchers. However, this research has typically focused on data sets collected via telephone, postal mail, or face-to-face interviews.

Robust Inference in Two-phase Sampling Designs with Application to Unit Nonresponse [PDF]

Scandinavian Journal of Statistics, 2016
AbstractInfluential units occur frequently in surveys, especially in business surveys that collect economic variables whose distributions are highly skewed. A unit is said to be influential when its inclusion or exclusion from the sample has an important impact on the sampling error of estimates.

Using Calibration Weighting to Adjust for Nonignorable Unit Nonresponse

Journal of the American Statistical Association, 2010
When calibration weighting is be used to adjust for unit nonresponse in a sample survey, the response/nonresponse mechanism is often assumed to be a function of a set of covariates, which we call “model variables.” These model variables usually also serve as the benchmark variables in the calibration equation. In principle, however, the model variables

Recalibration Estimation for Unit Nonresponse at the Two Levels Auxiliary Information

Communications for Statistical Applications and Methods, 2003
【In this paper we suggest the new calibration estimator, which is called to the recalibration estimator, and its variance estimator using two-phase sampling technique according to the auxiliary information having strong correlation with the variable of interest under the unit nonresponse. In this unit nonresponse situation, an available information may

The Influence of a Person’s Digital Affinity on Unit Nonresponse and Attrition in an Online Panel

Social Science Computer Review, 2018
Research has shown that the non-Internet population is hesitant to respond to online survey requests. However, also subgroups in the Internet population with low digital affinity may hesitate to respond to online surveys. This latter issue has not yet received much attention by scholars despite its potentially detrimental effects on the external ...

Entwicklung des Unit-Nonresponse in der Bundesrepublik

1997
In der Bundesrepublik scheint weitgehender Konsens in Hinsicht auf das Ansteigen des Nonresponse im Laufe der Zeit zu bestehen. Eine von Hansen (1988:400) durchgefuhrte Umfrage bei den ADM-Instituten ergab, das die Institute in der Regel eine rucklaufige Ausschopfungsquote in den letzten Jahren feststellen.
