Abstract:

Contingency tables have provided an initial ground for the growth of algebraic statistics, with some of the earliest applications tied to the problems of statistical disclosure limitation (SDL), that is of data privacy and confidentiality. In this talk I will briefly review links between algebraic statistics, log-linear models and disclosure limitation strategies associated with contingency tables which protect against the identification of individuals associated with counts in the tables. I will illustrate the linkages through an example, and also present some new results relevant for counting, sampling and optimizing over the space of possible contingency tables in the applied SDL context.
