Randomized Response Survey on drugs use
Description
This data set contains observations from a randomized response survey conducted in a university to investigate drugs use.
The sample is drawn by cluster sampling with the probabilities proportional to the size.
The randomized response technique used is the Horvitz-UB model (Chaudhuri, 2011) with parameters p_1=0.6 and p_2=0.7.
