Explaining Income Nonresponse: A Case Study by Means of the British Household Panel Study (BHPS)

Many validation studies deal with item nonresponse and measurement error in earning data. In this paper, we explore motives of respondents for the failure to reveal earnings using the British Household Panel Study (BHPS). The BHPS collects socio-economic information of private households in Great Britain. We explain the evolution of income-nonresponse in the BHPS and demonstrate the importance of a ...

Rethinking the Dependent Variable in Voting Behavior: On the Measurement and Analysis of Electoral Utilities

As a dependent variable, party choice did not lend itself to analysis by means of powerful multivariate methods until the coming of discrete-choice models, most notably conditional logit and multinomial logit. These methods involve estimating effects on party preferences (utilities) that are post hoc derived from the data, but such estimates are plagued by a number of difficulties. These difficulties ...

A Comparison of Different Imputation Rules

Alternative Measures of the Explanatory Power of General Multivariate Regression Models

In this paper R 2-type measures of the explanatory power of multivariate linear and categorical probit models proposed in the literature are reviewed and their deficiencies discussed. It is argued that a measure of the explanatory power should take into account the components which are explicitly modelled when a regression model is estimated while it should be indifferent to components not explicitly ...

Taking "Don't Knows" as Valid Responses: A Complete Random Imputation of Missing Data

Incomplete data is a common problem of survey research. Recent work on multiple imputation techniques has increased analysts' awareness of the biasing effects of missing data and has also provided a convenient solution. Imputation methods replace non-response with estimates of the unobserved scores. In many instances, however, non-response to a stimulus does not result from measurement problems that ...

Automatic Identification of Faked and Fraudulent Interviews in Surveys by Two Different Methods

This paper presents two new tools for the identification of faking interviewers in surveys. One method is based on Benford's Law, and the other exploits the empirical observation that fakers most often produce answers with less variability than could be expected from the whole survey. We focus on fabricated data, which were taken out of the survey before the data were disseminated in the German Socio-Economic ...

Intervieweffekte bei der Erhebung des Körpergewichts: die Qualität von umfragebasierten Gewichtsangaben

While surveying measured weight is widely unpractical in national samples, self-reported weight is a simple and inexpensive method of collecting data. This paper deals with data quality of reported body weight in the German Socio-Economic Panel Study (SOEP). Previous research shows that data on reported body weight are plagued by systematic misreporting. This bias is said to be the consequence of the ...
