Thus, to calculate an actual false accusation rate, we need data for three values in equation (4): the drug use rate for the target group of workers; the false positive rate of the laboratory doing the tests; and the true positive rate of the laboratory doing the tests.
By estimating confidence of signatures generated from each frame and using the confidence for sequence identification, the technology achieves a high detection rate (*6) with a very low false positive rate (*7).
The ability to measure multiple analytes in the same analysis enabled the calculation of the phenylalanine/tyrosine molar ratio, which reduced false positive rates a 100-fold.
The sensitivity of Harmony was significantly higher with a false positive rate 90-fold lower than standard screening.
MSS has a false positive rate of approximately 5% and a false negative rate of up to 15%.
Both the CARE and NEXT trials also evaluated cfDNA testing vs standard screening for diagnosis of trisomy 13 and 18 and found higher PPVs and lower false positive rates for cfDNA compared with traditional screening.
Figure 6.5 illustrates the results of false positive rate on matching the patterns using RPPM method is compared with two state-of-the-art methods SVD and MSR.
By setting a false positive rate of one per million non-malicious web links, deep-learning can achieve a detection rate of 72 per cent for new malicious web links that do not appear on previously announced threat lists.

In the experiments, LTM reached the minimum false positive rate of 0.0046% when FBA reached only 0.0367%, which means that LTM has up to 500% better detection score than the classic FBA method with the similar level of false positive rates.
Finally, the tool examines the false positive rate across different groups and enforces a user-determined equal rate of false positives across all groups.
