SOME ASPECTS OF DATA ANALYSIS UNDER CONFIDENTIALITY PROTECTION
A main focus of recent research in many government agencies (such as US Census Bureau) is the novel creation and valid analysis of perturbed data which are either magnitude or categorical in nature. US Census Bureau mandate calls for protection of confidential data, avoidance of identity disclosure, and valid analysis of eventually released data! Often some form of perturbation of original data is used through differential privacy approach, swapping, noise addition/multiplication, pramming (for qualitative variables), creating singly or multiply imputed synthetic data, and so on Research is needed to produce such variations of the original data, provide valid statistical analysis of the released data, and evaluate the level of confidentiality protection supplied by the underlying new data generation methods.
In these lectures I will touch upon two aspects of data perturbation: noise multiplication and synthetic data, and elaborate on how to create and sensibly analyze such perturbed data with some examples. Time permitting, I will also present some severe consequences of model misspecifications.
