The conditional distribution of Y when n = 11 is shown in Fig. 1.
From the above distributional identity it is clear that the split sample method relies on the sufficient statistic X as well
as an additional random variable Y, and that it therefore can be considered to amount to adding discrete noise to binomial
data. We note however that the noise term Y is a deterministic function of the sequence X1, . . . , Xn. Conditioned on the
sequence, it is therefore more natural to think of ˜ X as resulting from splitting the sample rather than adding noise to X.
