Paired comparison product testing when individual preferences are stochastic
The preference of an individual in a paired comparison product test is stochastic, i.e. the probability p, that he will prefer one of the two alternatives, is not 0 or 1, but lies somewhere between these values. It is shown that the distribution of p, when approximated by a beta distribution, can be obtained by means of a replicated paired comparison product test.
