false positive rate (1 specificity)

What Factors Influence the False Positive Rate?

Several factors can influence the false positive rate:
Test Sensitivity - While sensitivity measures the ability to correctly identify those with the disease, highly sensitive tests might have lower specificity, thereby increasing the FPR.
Prevalence of the Disease - In low-prevalence settings, even tests with high specificity can yield a relatively high number of false positives.
Cut-off Values - The threshold set for a test can impact FPR. Lower thresholds may increase the number of false positives.
