  • scorer: Scoring function.

PortfolioOptimisers.NonCombOptCV Type
julia
const NonCombOptCV = Union{<:KFold, <:WalkForwardEstimator}

Alias for non-combinatorial optimisation cross-validation schemes.

Matches either a KFold or a WalkForwardEstimator. Used for dispatch in routines that require sequential or fold-based (non-combinatorial) cross-validation.
