The sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV), and false positive rates (FPR) and false negative rates
(FNR) of preoperative sampling histological diagnosis when compared to hysterectomy findings as gold standard were 58.3%, 90%, 70%, 81.8%, 30.1%, and 18.2% (Table 2).
The detection rate equals 86.77%, classification precising rate equals 89.23%, false positive rate equals 8.72, false negative rate
equals 13.23, classification error rate equals 10.77, and AUC equals 86.32.
Results compiled over the past seven years at the Metropolitan Hospital, Cape Coast, are indicative of both false positive and false negative rates
, which are biologically significant and could have dire consequences on infants and mothers.
Third, since there is a high false negative rate
of 20%, one negative mycobacterial urine culture does not mean the absence of genitourinary TB.
False Negative Rate
(FNR) is the rate of the number of foreground pixels misclassified into background to the total number of foreground pixels in the ground truth image.
Equations (1), (2) and (3) define true positive rate (TPR), which is also referred to as sensitivity, false negative rate
(FNR) and accuracy (A):
Table 1 documents a comparative analysis on detection rate, false positive rate, and false negative rate
between three existing methods and our two proposed methods using Gentle Adaboost haar-cascade and train-cascade.
We evaluated the efficacy of all these techniques empirically (error of estimation of the fetal heart rate, sensitivity, and false negative rate
(2) to determine the false negative rate
of the TST with IGRA as reference standard for different TST induration thresholds;
The latter finding had a false negative rate
of 1% for cases rated 0, and 2.7% for the cases rated 1+, along with a percentage of false positives of 1.5% for the cases rated as 3+.
The false negative rate
(M0 grading by optometrist but M1 by ophthalmologist) was 4/16 or 25% (sensitivity 75%).
But it's important to remember that there is a false negative rate
of 10 percent, meaning that 10 percent of breast cancers are not seen on mammogram.
