# predictive value

Also found in: Dictionary.

## pre·dic·tive val·ue

an expression of the likelihood that a given test result correlates with the presence or absence of disease. A positive predictive value is the ratio of patients with the disease who test positive to the entire population of those with a positive test result; a negative predictive value is the ratio of patients without the disease who test negative to the entire population of those with a negative test result.

## predictive value

P value Decision-making A value that predicts the likelihood that a result from a test reflects the presence or absence of a disease. Cf ROC curve.

## pre·dic·tive va·lue

(prē-dik'tiv val'yū)
An expression of the likelihood that a given test result will correlate with the presence or absence of disease. A positive predictive value is the ratio of patients with the disease who test positive to the entire population of people with a positive test result; a negative predictive value is the ratio of patients without the disease who test negative to the entire population of people with a negative test result.

## predictive value

a measure used by clinicians to interpret diagnostic test results. See also sensitivity, specificity.

positive predictive value
the probability that a patient with a positive test result really does have the condition for which the test was conducted.
negative predictive value
the probability that a patient with a negative test result really is free of the condition for which the test was conducted.

In the prediction process, because it is dynamic prediction for the model of sequence, except for the first prediction is the predictive value using the actual value of explanatory variables, every prediction behind is using recursive prediction method and putting the anterior value from dynamic element (Lagged explanatory variables) into the predictive formula to predict the value of next round.
