Struct VarSelectConfig 

#[non_exhaustive]
pub struct VarSelectConfig {
    pub ncomp: usize,
    pub penalty: VarSelectPenalty,
    pub lambda: f64,
    pub max_iter: usize,
    pub epsilon: f64,
    pub lambda_n_grid: usize,
}

Configuration for variable_selection.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

ncomp: usize

FPC components per predictor. 0 = auto-select via GCV (default: 3).

penalty: VarSelectPenalty

Group penalty type (default: VarSelectPenalty::GroupLasso).

lambda: f64

Penalty weight λ. 0.0 = CV-select over a grid (default: 0.0).

max_iter: usize

Maximum coordinate-descent iterations (default: 100).

epsilon: f64

Convergence threshold on max coefficient delta (default: 1e-5).

lambda_n_grid: usize

Grid size for λ selection (default: 20).
