Lidar false positive rate

Web17. nov 2024. · I found this blogpost by googling for “significance false positive rate”. I noticed that what you call “false positive rate” is apparently called “false discovery rate” elsewhere. According to Wikipedia, the false positive rate is the number of false positives (FP) divided by the number of negatives (TN + FP). WebROC curves are used in clinical biochemistry to choose the most appropriate cut-off for a test. The best cut-off has the highest true positive rate together with the lowest false positive rate. As the area under an ROC curve is a measure of the usefulness of a test in general, where a greater area means a more useful test, the areas under ROC ...
