What is the relationship between sensitivity and threshold

Statistics 102 (colin rundel) lec 21 april 17, 2013 14 / 28.Relationship between sensitivity and speci city threshold 0.75 0.625 0.5 0.375 0.25 sensitivity 0.074 0.106 0.136 0.305 0.510 speci city 0.997 0.995 0.995 0.963 0.936 l l l l lIn this experiment we will test the sensitivity of five separate areas of the skin:It can be thought of like this:Low threshold equals high sensitivity and vice versa.Threshold determines how much motion is required to trigger an event.

It is recommended to select a sensitivity between 30~70.The relationship between accuracy, sensitivity, specificity, and threshold.There is no clear cut answer to sensitivity/threshold settings that can truly eliminate false positives, while maintaining that they trigger as desired, for all cases.The figure below depicts the relationship between disease prevalence and predictive value in a test with 95% sensitivity and 95% specificity:Tolerance varies much more widely across subjects and depends on prescribed medications.
