Bounds for cell entries in contingency tables induced by fixed marginal totals with applications to disclosure limitation
We describe new results for upper and lower bounds on the entries in multi-way tables of counts based on a set of released and possibly overlapping marginal tables which have practical importance for assessing disclosure risk. In particular, we present a generalized version of the shuttle algorithm proposed by Buzzigoli and Giusti that is proven to compute sharp integer bounds for an arbitrary ...
متن کاملCell Bounds in Two-Way Contingency Tables Based on Conditional Frequencies
Statistical methods for disclosure limitation (or control) have seen coupling of tools from statistical methodologies and operations research. For the summary and release of data in the form of a contingency table some methods have focused on evaluation of bounds on cell entries in k-way tables given the sets of marginal totals, with less focus on evaluation of disclosure risk given other summa...
متن کاملBounds for Cell Entries in Two-Way Tables Given Conditional Relative Frequencies
In recent work on statistical methods for confidentiality and disclosure limitation, Dobra and Fienberg (2000, 2003) and Dobra (2002) have generalized Bonferroni-Fréchet-Hoeffding bounds for cell entries in k-way contingency tables given marginal totals. In this paper, we consider extensions of their approach focused on upper and lower bounds for cell entries given arbitrary sets of marginals a...
متن کاملStatistical Disclosure Limitation with Released Marginals and Conditionals for Contingency Tables
The goal of statistical disclosure limitation is to develop methods and tools that while preserving confidentiality can provide access to useful statistical data, not just a few numbers. In this paper we consider releases from contingency tables in the form of marginal counts and observed conditional frequencies. We link data utility to log-linear models, and evaluation of disclosure risk to bo...
متن کاملAlgebraic Statistics and Contingency Table Problems: Log-linear Models, Likelihood Estimation, and Disclosure Limitation
Contingency tables have provided a fertile ground for the growth of algebraic statistics. In this paper we briefly outline some features of this work and point to open research problems. We focus on the problem of maximum likelihood estimation for log-linear models and a related problem of disclosure limitation to protect the confidentiality of individual responses. Risk of disclosure has often...
