Leave-one-out cross-validation for ordered multiclass ODA.

Usage

oda_loo_multiclass_ordered(
  x,
  y,
  w0,
  priors_on_eff,
  degen,
  K_segments,
  miss_codes = NULL,
  cut_value_mode = c("midpoint", "lower", "upper"),
  grid_mode = c("fixed", "refit"),
  boundary_mode = c("megaoda_halfopen", "right_closed"),
  loo_use_samplerep = FALSE,
  loo_return_folds = FALSE,
  loo_priors_mode = c("fold", "global")
)

Arguments

x, y: Attribute and class vectors.
w0: Raw case weights.
priors_on_eff: Logical.
degen: Logical.
K_segments: Number of segments.
miss_codes: Optional missing codes.
cut_value_mode: "midpoint","lower","upper".
grid_mode: "refit" (true per-fold rebuild) or "fixed" (global grid).
boundary_mode: "megaoda_halfopen" or "right_closed".
loo_use_samplerep: Include samplerep in fold selection.
loo_return_folds: Return per-fold rules and debug info.
loo_priors_mode: "fold" (renorm each fold) or "global" (global wts).

Value

List with allowed, confusion_raw, confusion_weighted, y_pred, and optional fold_rule, fold_debug, fold_best_enum_id.
