[no-lexicon]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. Here, we consider the approach by Chipperfield and Chambers (2015), further referred to as CC.
