Applied Notes of Sampling Survey for Sensitive Questions

This paper probes the problems from the survey of sensitive questions. The likelihood and Bayesian estimation of the proportions of answers to the questions and the cross proportions between the questions is given in the case that one of the pair of the sensitive question and the match question in the questionaire with more than one sensitive question is picked respectively independantly and randomly. In addition, I consider the case that more than one of the pair of the sensitive question and the match question are answered once a radomization is also considered.
