Regression Analysis Under Incomplete Linkage, Gunky Kim, Raymond Chambers Nov 2012

Regression Analysis Under Incomplete Linkage, Gunky Kim, Raymond Chambers

Dr Raymond Chambers

Most probability-based methods used to link records from two distinct data sets corresponding to the same target population do not lead to perfect linkage, i.e. there are linkage errors in the merged data. Further, the linkage is often incomplete, in the sense that many records in the two data sets remain unmatched at the completion of the linkage process. This paper introduces methods that correct for the biases due to linkage errors and incomplete linkage when carrying out regression analysis using linked data. In particular, it focuses on the case where one of the linked data sets is a sample …


Regression Analysis Under Probabilistic Multi-Linkage, Gunky Kim, Raymond Chambers Nov 2012

Regression Analysis Under Probabilistic Multi-Linkage, Gunky Kim, Raymond Chambers

Dr Raymond Chambers

"Linkage errors can occur when probability-based methods are used to link records from two distinct data sets corresponding to the same target population. Current approaches to modifying standard methods of regression analysis to allow for these errors only deal with the case of two linked data sets and assume that the linkage process is complete, that is, all records on the two data sets are linked. This study extends these ideas to accommodate the situation when more than two data sets are probabilistically linked and the linkage is incomplete."
