Struct SparseColMoments

Source

pub struct SparseColMoments {
    pub indices: Vec<u32>,
    pub values: Vec<f32>,
    pub mean: f64,
    pub sd: f64,
}

Expand description

One sparse column reduced to what sparse_pairwise_correlations needs.

The stored entries are kept as they arrive; nothing here densifies, so the memory is O(nnz) per column rather than O(n_rows).

Fields§

§indices: Vec<u32>

Row indices of the stored entries. Ascending order is not required.

§values: Vec<f32>

Values at those indices. The raw values for Pearson, the zero-shifted ranks for Spearman. Every non-stored position is exactly zero in both cases, which is what makes the closed forms below valid.

§mean: f64

Mean over all n_rows entries, structural zeros included.

§sd: f64

Standard deviation over all n_rows entries, sample (n - 1) denominator.
