Once we observe x and compute a sufficient statistic T(x), the original data x do not contain any further information concerning q and can be discarded, i.e., T(x) is all we need regarding q. If we do need x, we can simulate a sample y from P(X = yjT(X) = T(x)) since it is known; the observed y may not
