Statistically Valid Inferences from Differentially Private Data Releases, II: Extensions to Nonlinear Transformations
Georgina Evans and Gary King. Working Paper. “Statistically Valid Inferences from Differentially Private Data Releases, II: Extensions to Nonlinear Transformations”.Abstract

We extend Evans and King (Forthcoming, 2021) to nonlinear transformations, using proportions and weighted averages as our running examples.

Paper
Statistically Valid Inferences from Privacy Protected Data
Georgina Evans, Gary King, Margaret Schwenzfeier, and Abhradeep Thakurta. Working Paper. “Statistically Valid Inferences from Privacy Protected Data”.Abstract
Unprecedented quantities of data that could help social scientists understand and ameliorate the challenges of human society are presently locked away inside companies, governments, and other organizations, in part because of privacy concerns. We address this problem with a general-purpose data access and analysis system with mathematical guarantees of privacy for research subjects, and statistical validity guarantees for researchers seeking social science insights. We build on the standard of ``differential privacy,'' correct for biases induced by the privacy-preserving procedures, provide a proper accounting of uncertainty, and impose minimal constraints on the choice of statistical methods and quantities estimated. We also replicate two recent published articles and show how we can obtain approximately the same substantive results while simultaneously protecting the privacy. Our approach is simple to use and computationally efficient; we also offer open source software that implements all our methods.
