Usually the Theory of Signal Detection is used to estimate summary statistics, d' and β from measured false alarm and hit rates. Here we estimate d' and β directly and thus can estimate p(F) and p(M). This is possible even for very rare errors where it is difficult or impossible to obtain direct measures of error probabilities. An example of the model is provided using data collected from nuclear power plant personnel. The predicted error rates depend on the quality of the displays, and from the examples given the error rates appear quite close to those predicted by Swain and Guttman (1980).
