如何在缺陷跟踪中计算误报率？ 在我总共有334个bug的情况下，其中57个是“不是问题”类型

Question

How to calculate False Positive rate in a scenario where I have 334 bugs in total out of which 57 are Not an Issue type? I believe 57 are false positives in this scenario

Answer 1

The term false positive ratio, also known as the false alarm ratio, usually refers to the probability of falsely rejecting the null hypothesis for a particular test. The false positive rate is calculated as the ratio between the number of negative events wrongly categorized as positive (false positives) and the total number of actual negative events (regardless of classification).

The false positive rate is FP/N = FP/FP+TN

where FP is the number of false positives, TN is the number of true negatives and N=FP+TN is the total number of negatives.
