Module Modelkit.Leave_one_out

Exhaustive single-row testing in source order.

type t
type params = unit
val create : unit -> t

Requires at least two rows. Each row is tested once against all remaining training rows. RNG, targets, and groups are ignored. Views are emitted eagerly and require quadratic total index storage. Single-row scores such as R-squared can be undefined; select an appropriate scorer.
