A probabilistic modellin g framework based on the Poisson log-linear model is demonstrated for quan tifying disclosure risk in terms of population uniqueness when population counts are unknown. This method does not account for measurement error ari sing either naturally from survey processes or purposely introduced as a p erturbative disclosure limitation technique. The probabilistic modelling f ramework for assessing disclosure risk is expanded to take into account th e misclassification/ perturbation and demonstrated on sample microdata whi ch has undergone a perturbation procedure. Finally\, we adapt the probabil istic modelling framework to assess the disclosure risk of non-random samp les from sub-populations and show some initial results.\n\nThis is joint w ork with Prof. Chris Skinner of the London School of Economics and Politic al Science.\n\nNatalie Shlomo is Professor of Social Statistics at the Uni versity of Manchester and currently an organiser of the programme Data Lin kage and Anonymisation at the Isaac Newton Institute of Mathematical Scien ces. Her research interests are in survey methodology and official statist ics. She is the UK principle investigator for several collaborative grants from the 7th Framework Programme of the European Union all involving rese arch in improving survey methods and dissemination. She is an elected memb er of the International Statistical Institute and a fellow of the Royal St atistical Society.\n\nAll welcome! Refreshments will be served before the talk.\n\nThere are two spare tickets for dinner with the speaker after the event. If you would like to come to hall at Trinity with Prof Shlomo\, pl ease RSVP to Khyla (kk538) by 3pm Saturday. LOCATION:Room 6\, Mill Lane END:VEVENT END:VCALENDAR
