This paper examines the usefulness of testing the conformity of macroeconomic data with Benford's law as indicator of data quality. Most of the macroeconomic data series tested conform with Benford's law. However, questions emerge on the reliability of such tests as indicators of data quality...

This paper focuses on fraud detection in surveys using Socio-Economic Panel (SOEP) data as an example for testing newly methods proposed here. A statistical theorem referred to as Benford's Law states that in many sets of numerical data, the significant digits are not uniformly distributed, as...

This paper presents an approach integrating data quality into the business intelligence chain in the context of customer-relationship management (CRM) applications at EDF (Electricité de France), the major electricity company in France. The main contribution of this paper is the definition and...

This paper examines the implication of the move to CAPI for data quality by analyzing the conversion from PAPI to CAPI of a subsample of the German Socio-Economic Panel (SOEP) which was done within an experimental design. The 2000 addresses for the sample E of SOEP were split into two subsamples...

In many countries population estimates are unreliable at higher ages. In this article a method for producing an independent estimate of population aged 90+ from data on deaths and population estimates at lower ages is developed. The method builds on an indirect mortality estimate from deaths...
