pub type ColumnNormalizationStats<F> = (Option<Vec<F>>, Option<Vec<F>>);

Computed column centers and raw scales, respectively.

An inactive normalization component is None. Present vectors have one entry per column. Raw scales may be zero; crate::LazyMatrix::new replaces exact zeros with one while preserving nonfinite values.
