摘  要：In business research and social sciences surveys, it is not uncommon to collect responses to sensitive questions. Randomized response techniques have been shown to be a useful statistical method to protect respondents’ privacy while being able to elicit truthful answers to sensitive questions. However, when the number of survey questions is not small, analyzing relationship among different responses becomes nontrivial. In this paper, a Bayesian approach is proposed aiming at performing multivariate analysis of multiple responses where some of them are sensitive. To deal with high-dimensionality issues when the number of questions is large, Bayesian shrinkage idea is adopted. Our method is illustrated by simulation and a business survey on information security.
