Signal Detection Theory
#Computers #Biology #Math
| Signal State | Positive Detection | Negative Detection |
|---|---|---|
| Present | True Positive/Hit (TP) | False Negative/Miss/Type II Error (FN) |
| Absent | False Positive/False Alarm/Type I Error (FP) | True Negative (TN) |
| Let $\displaystyle +$ be the event of a positive detection, $\displaystyle -$ be the event of a negative detection, $\displaystyle P$ be the event of the signal being present, and $\displaystyle A$ being the event of the absence of the signal |
