Description
Summary:The problem is in the estimation of the fraction of population with a sensitive characteristic. We consider the Item Count Technique an indirect method of questioning designed to protect respondents' privacy. The exact confidence interval for the sensitive fraction is constructed. The length of the proposed CI depends on both the given parameter of the model and the sample size. For these CI the model's parameter is established in relation to the provided level of the privacy protection of the interviewee. The optimal sample size for obtaining a CI of a given length is discussed in the context.
