A new stochastic randomized response model

Abstract. The collection of data through personal interview surveys on sensitive issues such as induced abortions, drug abuse and family income is a serious issue in social sciences. Warner (1965) was the first to propose an ingenious method to collect information on such questions without disclosing the privacy of the respondents, which is called randomized response technique. In the present investigation, a new stochastic randomized response technique is proposed that elicits greater cooperation from the respondents, and can be made more efficient than Warner's (1965) and Mangat and Singh (1990) method by selecting certain parameters of the proposed randomization device.
