Which of the following statements pertaining to the index of predictive association is
FALSE?
a. The index of predictive association is useful when nominally scaled data are available
and when we are interested in the degree of improvement in predictions of the criterion
variable brought about by considering the classes of the predictor variable.
b. The index of predictive association is equal to one, if the B classification is of no
help in predicting the A classification.
c. The index of predictive association gA.B.measures the relative decrease in the
probability of error by taking account of the B classification in predicting the A
classification over the error of prediction with the B classification unknown.
d. a and b above
e. a and c above
