Module Modelkit.Repeated_stratified_k_fold

Repeated shuffled stratified K-fold, with five folds and ten repetitions by default. Uses the class allocation and feasibility rules of Stratified_k_fold; rare classes can be absent in a fold. Splits are repetition-major, then fold-major, and indices retain source order. Extending the repetition count preserves earlier repetitions. Random streams are deterministic for the same input and seed, independent of execution scheduling; they do not reproduce NumPy random streams. Groups do not constrain these splits; use group-aware splitting when group exclusion is required.
