Description: The Hierarchical Neyman-Pearson (H-NP) classification framework
    extends the Neyman-Pearson classification paradigm to multi-class settings
    where classes have a natural priority ordering. This is particularly useful
    for classification in unbalanced dataset, for example, disease severity
    classification, where under-classification errors (misclassifying patients
    into less severe categories) are more consequential than other
    misclassifications. The package implements H-NP umbrella algorithms that
    controls under-classification errors under user specified control levels
    with high probability. It supports the creation of H-NP classifiers using
    scoring functions based on built-in classification methods (including
    logistic regression, support vector machines, and random forests), as well
    as user-trained scoring functions. For theoretical details, please refer to
