This paper presents the results of a limited investigation which brings into focus the difficulties encountered in developing exact distribution-free methods for stratified simple random sampling. It ...

Discrepancy theory investigates the uniformity of distributions by quantifying the deviation between the empirical distribution of a finite set of points and the uniform distribution. In numerical ...
