Description Details Author(s) See Also
This package provides functions for quantifying the performance of a diagnostic test (or any other binary classifier) by calculating and plotting the distributions in cases and noncases of the weight of evidence favouring case over noncase status.
To use it, you should have computed on a test dataset (or on test folds used for cross-validation:
1. The prior probability of case status (this may be just the frequency of cases in the training data.
2. The posterior probability of case status (using the model learned on the training data to predict on the test data)
3. The observed case status (coded as 0=noncase, 1=case).
