TABLE IV. The Expected Relative Cost of the Dorfman Two-Stage Algorithm With Its Optimal Group Size in Table III, and the Lowest Expected Relative Cost of -Regular in [15]. The Numbers Given in Boldface are the Expected Relative Costs of Dorfman's Two-Stage Algorithm of the Smallest Values of That Outperform Those of the -Regular Pooling Matrices Under the Same Prevalence Rate .
