Efficient Rounding of Approximate Designs
讨论了将近似设计取整为给定样本量n的精确设计的离散化方法，提出了一种在多种最优性准则下效率损失最小的唯一方法——高效取整法。
Discretization methods to round an approximate design into an exact design for a given sample size n are discussed. There is a unique method, called efficient rounding, which has the smallest loss of efficiency under a wide family of optimality criteria. The efficient rounding method is a multiplier method of apportionment which otherwise is known as the method of John Quincy Adams or the method of smallest divisors.
