Randomized Response Methods

2014
In survey research it is often problematic to ask people sensitive questions because they may refuse to answer or they may provide a socially desirable answer that does not reveal their true status on the sensitive question. To solve this problem Warner (1965) proposed randomized response (RR). Here a chance mechanism hides why respondents say “yes” or

Optionally Randomized Response Techniques

Calcutta Statistical Association Bulletin, 1985
It is shown that for sensitive and confidential characters the usual loss of efficiency due to randomized rather than direct response may be partially recouped if the interviewees are left free to opt for either mode of response. Specific results are derived with multinomial sampling.

Nonparametric response‐adaptive randomization for continuous responses

Pharmaceutical Statistics, 2018
Many response‐adaptive randomization procedures have been proposed and studied over the past few decades. However, most of these procedures are based on parametric structure and do not directly apply to nonparametric models. In this paper, we propose a response‐adaptive randomization procedure based on Mann‐Whitney U test statistic.

Optimal Randomized Response Models

International Statistical Review / Revue Internationale de Statistique, 1976
Summary Randomized response methods allow different kinds and degrees of privacy depending upon models and parameters. A theoretical approach to efficiency is suggested based on minimizing variance for given privacy requirements. Privacy requirements are indexed by measures from information theory, variances are expressed in terms of these measures ...

A Controlled Randomized Response Technique

Evaluation & the Health Professions, 1993
The randomized response survey technique appears to be suitable for studies of sensitive sexual behaviors, particularly inAIDS-related research. However, existing methods provide only estimates of group statistics, not of individual information. Additionally, the popular "unrelated question" approach requires the knowledge of the parameters of the ...

An Alternative Randomized Response Procedure

Biometrika, 1990
SUMMARY The paper considers a new randomized response procedure. The proposed method requires the use of two randomization devices. The conditions when the proposed strategy will be more efficient than the usual Warner's strategy have been obtained for the cases when the respondents are truthful and when they are not completely truthful in their ...

Randomized response techniques

Model Assisted Statistics and Applications, 2014
Collection of data on sensitive characteristics from human populations is not an easy task. For example sensitive questions: (a) Are you an Alawite? (b) Are you gay? (c) Have you ever molested a child? (d) Have you underreported your income on your tax return? (e) Do you smoke marijuana?, and (f) Have you ever cheated on an exam?, etc.

Randomized Response Techniques: A Review

Statistica Neerlandica, 1987
Randomized response techniques (RRT) are well–known as tools to procure trustworthy survey data on confidential issues. A review is attempted here of mostly published accounts on RRT covering qualitative and quantitative characters. Conflicting criteria of efficient estimation and protection of privacy are discussed.
