Abstract

This paper proposes an
alternative randomized response technique by improving existing works on
tripartite randomized response technique (TRRT) using unrelated questions. To
improve the technique, this work studies TRRT under sampling with unequal
probabilities with or without replacement. The study of percentage relative
efficiency shows that the proposed estimator is far better than the Hybrid
Tripartite Randomized Response Technique with increase in the sensitive
character and that of the unrelated character.
In addition, conducting survey using both the proposed technique and direct
(traditional) technique shows that the proposed technique is more efficiency
than the direct technique of data collection.
