    Snippet: First of all, even if the underlying probability of positive samples is known, the actual number of positive samples in a total of N samples will have a standard deviation that scales as 1 √ ⁄ . This intrinsic uncertainty will be significant for small N. To check robustness to intrinsic uncertainty in the actual frequency of positive samples, we simulate both algorithms for N=128. We find that this introduces a standard deviation of about 10 .....
    Document: First of all, even if the underlying probability of positive samples is known, the actual number of positive samples in a total of N samples will have a standard deviation that scales as 1 √ ⁄ . This intrinsic uncertainty will be significant for small N. To check robustness to intrinsic uncertainty in the actual frequency of positive samples, we simulate both algorithms for N=128. We find that this introduces a standard deviation of about 10 tests, and that this variability is in practice roughly independent of p and comparable between both methods, though slightly lower in the method of one-time pooling (Fig 2) .
