WebSignal Detection Theory. "Threshold" doesn't exist or is arbitrary. Unify detection and discrimination. Dice example or tumor detection example. Detectability. Outcomes: hit, … WebPS is traditionally modeled under high threshold theory (HTT); however, tests have shown that HTT is incorrect and that signal detection theory (SDT) is the better framework for modeling summation. Modeling the equivalent of PS under SDT is, however, relatively complicated, leading many investigators to use Monte Carlo simulations for the predictions.
