Demo of Randomized Response model
Suppose you want to estimate the proportion of cheaters among students. Nobody will confess that he/she cheated. The randomized response model offers the plausible deniability for test takers.
The process goes as follows:
- Student comes up with an answer (cheating or working it through himself; this is hidden)
- Student tosses two fair coins
- if coin #1 is heads, he faitfully reports whether cheating took place
- else:
- if coin #2 is heads: report cheating
- else: report no cheating
The program generates synthetic dataset given number of examples and the true cheating proportion.
The program code is BSD licensed.
