Functions identify\noptimal subsets of PCL-5 items that maintain diagnostic\naccuracy while reducing assessment burden. Includes tools for\nboth hierarchical (cluster-based) and non-hierarchical symptom\ncombinations, calculation of diagnostic metrics, and comparison\nwith standard DSM-5 criteria. Model validation is conducted\nusing holdout and cross-validation methods to assess robustness\nand generalizability of the results. For more details see\nWeidmann et al.
