Abstract. We consider the problem of estimating the size and the mean value of a stigmatized quantitative characteristic of a sub-group (or hidden gang) in a finite population using a unified approach. The proposed method may be useful in estimating the proportion and the mean income of terrorists, "hijackers" or "freedom fighters" of a particular country, including those who operate across different countries.
Key words and phrases: Randomized response, sampling strategies, estimation of proportion, estimation of mean.
