Abstract:
1. A method for developing a predictive formula for calculating a quantitative measure of test accuracy, comprising: performing a behavioral test on a subject using a test system to measure a psychometric quantity; measuring the psychometric quantity to provide a test measurement of the psychometric quantity; measuring one or more quality indicators to provide one or more quality indicator measurements, the quality indicator being any variable that gives an indication of test accuracy; obtaining an independent measurement of the psychometric quantity for the subject, independent measurement being obtained separately from said behavioral test; calculating a difference between the test measurement and the independent measurement; determining a relationship between the quality indicator measurements and the difference between the test measurement and the independent measurement; and deriving a predictive formula based on the relationship, wherein the predictive formula can be used to calculate a quantitative measure of test accuracy in the behavioral test on future subjects.
