Data Linkage: From Theory to Practice

Description:

Course places are limited and registration by 13 May 2015 is strongly recommended.

Course No. ADRCE-Training013 Shlomo

Summary of Course:

The course will introduce basic concepts and methods of record linkage and will cover methodological and statistical aspects of this new emerging area. The course will provide theory and practical applications of deterministic and probabilistic approaches to record linkage including pre-matching processes, matching weights, types of errors in classification,  evaluation of the quality of linkage procedures, implementation of the E-M algorithm and an introduction to the analysis of linked datasets. By the end of the course, participants should have an understanding of record linkage techniques and be able to implement and evaluate record linkage procedures. The course does not assume any prior knowledge of record linkage and there will be  a session devoted to the revision of basic concepts in probability theory necessary to understand probabilistic record linkage. The course will have a strong practical emphasis and will include tutorials and a computer workshop to enable course participants to put the taught methods into practice. The software that will be used is SAS although no familiarity with SAS prior to the course is required. (This course is a more intensive course than the course ‘Introduction to Data Linkage').

Course Objectives:

• To develop an  understanding of the theory of  record linkage techniques
• To enable participants to implement a probabilistic record  linkage procedure
• To provide tools for  evaluating  and assessing the quality of the linked data

Course Content:

• Introduction and types of record linkage methods
• Sources for record linkage
• Examples of record linkage applications
• Pre-matching processes (data cleaning, standardizing and parsing of fields)
• Revision in probability and odds, Bayes Theorem and Hypothesis Testing
• Deterministic matching
• Probabilistic matching
• Field agreement weights and frequency based weights
• String Comparators
• Blocking variables
• Evaluation of record linkage
• Introduction to EM algorithm
• Introduction to the analysis of linked datasets
• Tutorials
• Computing lab in SAS  - applying record linkage to two datasets

Target Audience:

The course is aimed at researchers who need to gain an understanding of record linkage techniques. The course emphasizes putting theory into practice for those who need to carry out record linkage in their own work. Participants may be academic researchers in the social and health sciences or may work in government, survey agencies, official statistics, for charities or the private sector.

Pre-requisites:

The course does not assume any prior knowledge of record linkage and a special session will be devoted to the revision of probability theory necessary to understanding probabilistic record linkage. No familiarity with the software SAS will be assumed.

Course Materials:

Participants will receive course notes, tutorials and computing lab material.

Presenter:

Natalie Shlomo is a Professor in Social Statistics, School of Social Sciences at the University of Manchester. She has extensive knowledge of survey methods including data processing: record linkage, edit and imputation processes and statistical disclosure control.

Programme:

Available nearer to the course date.

The course will start with registration and coffee at 9.30 with formal teaching starting at 10.00 am on the first day (and on all subsequent days). The lectures will finish at 17:00 on each day. On the last day, there will be an opportunity for participants to ask questions on how to link their own datasets (you can bring your own data to the course if you wish).
