Efficient rounding

[JEQuidam]

By chance, is anyone here familiar with the paper entitled "Efficient rounding of approximate designs"? By Pukelsheim and Rieder, it was published in Biometrika, 1992 (79, 4, pp. 763-70). I would like to discuss it with someone who understands it in order to determine whether or not my take on it is correct.

 

It is a rather obscure subject; the paper's summary is as follows:

"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."
