abstract: 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) <https://doi.org/10.31219/osf.io/6rk72_v1>.
