Explore: Predictive Value Of Tests

Predictive value of tests is the probability of a target condition given by the result of a test, often in regard to medical tests. In cases where binary

negative predictive values (PPV and NPV respectively) are the proportions of positive and negative results in statistics and diagnostic tests that are

binary classification test can be measured with positive predictive value (PPV), also known as precision, and negative predictive value (NPV). The positive

be used: the accuracy of each predicted value is measured by its squared residual (vertical distance between the point of the data set and the fitted line)
