§components: Vec<Vec<f64>>

Principal components as row vectors, each of length n_features.

§explained_variance: Vec<f64>

Explained variance (eigenvalue) associated with each component.

§n_components: usize

Number of components extracted.

§n_features: usize

Number of features in the training data.
