  • Efficiency comparison of unrelated question models based on same privacy protection degree
    Statistical Papers, 2012
    Co-Authors: Sabrina Giordano, Pier Francesco Perri
    Abstract:

    In this study, the problem of estimating the proportion π _ A of people bearing a sensitive attribute A is considered. Three dichotomous unrelated question mechanisms which are alternative to the well-known Simmons’ model are discussed and their performance is evaluated taking into account both efficiency and respondent privacy protection. The variance of the estimators of π _ A is compared under equal levels of confidentiality measures introduced by Lanke ( 1976 ) and Leysieffer and Warner ( 1976 ).

  • Protection of privacy in efficient application of randomized response techniques
    Statistical Methods and Applications, 2009
    Co-Authors: Arijit Chaudhuri, Tasos C. Christofides, Amitava Saha
    Abstract:

    In estimating the proportion of people bearing a sensitive attribute A , say, in a given community, following Warner’s (J Am Stat Assoc 60:63–69, 1965) pioneering work, certain randomized response (RR) techniques are available for application. These are intended to ensure efficient and unbiased estimation protecting a respondent’s privacy when it touches a person’s socially stigmatizing feature like rash driving, tax evasion, induced abortion, testing HIV positive, etc. Lanke (Int Stat Rev 44:197–203, 1976), Leysieffer and Warner (J Am Stat Assoc 71:649–656, 1976), Anderson (Int Stat Rev 44:213–217, 1976, Scand J Stat 4:11–19, 1977) and Nayak (Commun Stat Theor Method 23:3303–3321, 1994) among others have discussed how maintenance of efficiency is in conflict with protection of privacy. In their RR-related activities the sample selection is traditionally by simple random sampling (SRS) with replacement (WR). In this paper, an extension of an essential similarity in case of general unequal probability sample selection even without replacement is reported. Large scale surveys overwhelmingly employ complex designs other than SRSWR. So extension of RR techniques to complex designs is essential and hence this paper principally refers to them. New jeopardy measures to protect revelation of secrecy presented here are needed as modifications of those in the literature covering SRSWR alone. Observing that multiple responses are feasible in addressing such a dichotomous situation especially with Kuk’s (Biometrika 77:436–438, 1990) and Christofides’ (Metrika 57:195–200, 2003) RR devices, an average of the response-specific jeopardizing measures is proposed. This measure which is device dependent, could be regarded as a technical characteristic of the device and it should be made known to the participants before they agree to use the randomization device.
