what are the four variables for diagnostic performance?
Positive predictive value
Negative predictive value
Complete the table for Diagnostic Performance Measures:
Positive Predictive Value
Negative Predictive Value
ie. SLAP tears on MRI
ability to detect disease;
ability to detect true positives
Ability to detect health:
ability to detect true Negatives
Define Positive Predictive Value:
Probability that the person has the disease given a positive test result
Proportion of positive tests that are TRUE POSITIVES
Define Negative Predictive Value
Probabiity that a person is healthy given a negative test result
Proportion of negative tests that are true negatives
How do Type I and Type II errors relate to false positives and false negatives?
