摘要：
The variance .sigma.2 from n pairs (Xi, Yi) which are independent normal random variables with unknown mean .mu.i and variance .sigma.2 was estimated. According to a marginal or conditional sufficiency argument, all useful information about .sigma.2 is contained in the differences Xi-Yi. Under fairly weak assumptions about the means, a considerable amount of information is also extractable from the sums Xi + Yi.
