30711 - RECORD LINKAGE

Conoscenze e abilità da conseguire

At the end of the course the student will know the methods for linking the information referred to the same statistical unit. This information belongs to different archives and the statistical unit is not identified by means of a code free of errors. The student will be able to use the exact matching, by means of deterministic and probabilistic record linkage and the basic tools of statistical matching.

• String similarity functions
• Blocking
• Fellegi-Sunter procedure
• Latent class model and its estimation via the EM algorithm
• Record linkage as an assignment problem
