Description: Provides tools for analyzing and optimizing PTSD
        (Post-Traumatic Stress Disorder) diagnostic criteria using
        PCL-5 (PTSD Checklist for DSM-5) and CAPS-5
        (Clinician-Administered PTSD Scale for DSM-5) data. Functions
        identify optimal subsets of PCL-5 items that maintain
        diagnostic accuracy while reducing assessment burden. Includes
        tools for both hierarchical (cluster-based) and
        non-hierarchical symptom combinations, calculation of
        diagnostic metrics, and comparison with standard DSM-5
        criteria. Model validation is conducted using holdout and
        cross-validation methods to assess robustness and
        generalizability of the results. For more details see Weidmann
        et al. (2025) <doi:10.31219/osf.io/6rk72_v1>.
