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.

Modalità di verifica e valutazione dell'apprendimento

The final exam for this module of the course is a written test that contains also questions of theory.

The online test will be performed via “Esami on Line” (EOL). Zoom will be the platform for identification and monitoring.

A final overall mark for the two modules of the course will be proposed to each student, after the exams for BOTH modules (record linkage and data bases).
