The term "percentage of predictive value" is not a commonly used term in statistics or data analysis. It is possible that you are referring to the concept of positive predictive value (PPV) or negative predictive value (NPV), which are measures used in medical testing or diagnostic accuracy.

Positive predictive value (PPV) is the proportion of true positive results among all positive test results, while negative predictive value (NPV) is the proportion of true negative results among all negative test results. These values are expressed as percentages.

For example, if a medical test has a PPV of 80%, it means that 80% of the positive test results are true positives. Similarly, if a test has an NPV of 90%, it means that 90% of the negative test results are true negatives.

It is important to note that the predictive value of a test can vary depending on the prevalence of the condition being tested for and the accuracy of the test itself.
