WebThe probability of a false-positive is also called the probability of false-alarm, which we will denote by P FA in the following examples. We will also denote the probabilty of detection (1 probability of a false-negative) by P D. The NP test maximizes P D subject to a constraint on P FA. 1.1 Detecting a DC Signal in Additive White Gaussian Noise

Webcriterion will rarely be exceeded on signal or noise trials. This will result in a low false-alarm rate, but also a low hit rate. The only way to increase the hit rate while reducing the false-alarm rate is to reduce the overlap between the signal and the noise distributions. Clearly, the hit and false-alarm rates reflect two factors: There are two main components to the decision-making process: information acquisition and criterion. Information acquisition:First, there is information in the CT scan.For example, healthy lungs have a characteristic shape. The presence of atumor might distort that shape.

WebHowever, the disappearance criterion showed the same sensitivity as the 70%-decrement criterion in IM (100%) and NIM (83%) surgeries for the motor deficit at 6 months after surgery. Moreover, it has the highest specificity for the motor deficits among diverse alarm criteria, from 24 hours to 6 months after surgery, in both the IM and NIM groups.
