Administrative data are used more and more in official statistics as a replacement for survey data.
When data sets are linked at individual level, for instance survey data with administrative data, often no unique linkage keys are available. In that case, probabilistic linkage may be used. With probabilistic linkage, linkage errors will occur. These errors may have impact on subsequent statistical analysis.
Estimation of bias and variance of the statistic of interest.
