title: 'PTSDdiag: Optimize PTSD Diagnostic Criteria'
version: 0.1.0
doi: 10.32614/CRAN.package.PTSDdiag
abstract: Provides tools for analyzing and optimizing PTSD (Post-Traumatic Stress
  Disorder) diagnostic criteria using PCL-5 (PTSD Checklist 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.
