Struct StandardizationInfo 

pub struct StandardizationInfo {
    pub x_mean: Vec<f64>,
    pub x_scale: Vec<f64>,
    pub y_mean: f64,
    pub y_scale: Option<f64>,
    pub intercept: bool,
    pub standardized_x: bool,
    pub standardized_y: bool,
}

Information stored during standardization, used to unstandardize coefficients.

This struct captures all the information needed to transform coefficients from the standardized space back to the original data scale.

Fields

• x_mean - Mean of each predictor column (length p)
• x_scale - Scale factor for each predictor column (length p)
• y_mean - Mean of response variable
• y_scale - Scale factor for response (optional, used for lambda path)
• intercept - Whether an intercept term was included
• standardized_x - Whether X was standardized
• standardized_y - Whether y was standardized

Fields

x_mean: Vec<f64>

Mean of each predictor column

x_scale: Vec<f64>

Scale factor for each predictor column

y_mean: f64

Mean of response variable

y_scale: Option<f64>

Scale factor for response (for lambda path construction)

intercept: bool

Whether an intercept was included

standardized_x: bool

Whether X was standardized

standardized_y: bool

Whether y was standardized
