Struct SampleSplitting 

pub struct SampleSplitting {
    pub n_folds: usize,
    pub n_rep: usize,
    pub seed: u64,
}

How observations are split for cross-fitting: n_rep independent repetitions of seeded K-fold splitting.

Fields

n_folds: usize

n_rep: usize

seed: u64

Implementations

impl SampleSplitting

pub fn draw(&self, n: usize) -> Result<Vec<Vec<Fold>>>

Draw the folds for every repetition. Repetition r uses its own seed derived from seed, so repetition 0 equals KFold::new(n_folds, seed).

pub fn draw_clustered( &self, clusters: &[Array1<i64>], ) -> Result<Vec<Vec<ClusterFold>>>

Cluster-level splits for every repetition (see crate::cluster).
