scripts default iconClinical Test Performance (Scripts) Publisher's description

This function calculate the performance, based on Bayes theorem, of a clinical test

This function calculate the performance, based on Bayes theorem, of a clinical test. The input is based on a 2x2 matrix (true positive, false positives; false negative, true negatives).

The Outputs are:
- Prevalence of disease
- Test Sensibility with 95% confidence interval
- Test Specificity with 95% confidence interval
- False positive and negative proportions
- Youden's Index
- Precision or Positive predictivity with 95% confidence interval
- Negative predictivity with 95% confidence interval
- Positive and Negative Likelihood Ratio
- F-Measure
- Test Accuracy or Potency
- Mis-classification Rate
- Error odds ratio
- Diagnostic odds ratio
- Discriminant Power
- Test bias
- Number needed to Diagnose (NDD)

Moreover, the function draws two plots (as you can see in the screenshot)

System Requirements:

MATLAB 7.6 (R2008a)
Program Release Status: New Release
Program Install Support: Install and Uninstall
