The nomographic display of the individual and cumulative inputs is evaluated stepwise via the calculation of likelihood ratios applied incrementally with a Fagan's Nomogram (Fagan TJ; 1975) [17] to produce an overall predictive index beginning with a calculated base rate, and combining the results of the other measures, in either an additive or ...

It was designed by Dr. Donald Macnab and Shawn Bakker of Psychometrics Canada.The questionnaire is designed to identify personality traits that relate to work performance; it takes most people 10 minutes to complete.
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
Although concurrent and predictive validity are similar, it is cautioned to keep the terms and findings separated. "Concurrent validity should not be used as a substitute for predictive validity without an appropriate supporting rationale." [3] Criterion validity is typically assessed by comparison with a gold standard test. [4]
A typical predictive validity for an employment test might obtain a correlation in the neighborhood of r = .35. Higher values are occasionally seen and lower values are very common. Nonetheless, the utility (that is the benefit obtained by making decisions using the test) provided by a test with a correlation of .35 can be quite substantial ...
