Bayesian Pseudo Posterior Mechanism under Asymptotic

Terrance D Savitsky, Matthew R Williams, and Jingchen Hu


We illustrate our pseudo posterior mechanism on the sensitive family income variable from the Consumer Expenditure Surveys database published by the U.S. Bureau of Labor Statistics. We show that utility is better preserved in the synthetic data for our pseudo posterior mechanism as compared to the EM, both estimated using the same non-private synthesizer, due to our use of targeted downweighting.
