Struct LambdaPathOptions 

pub struct LambdaPathOptions {
    pub nlambda: usize,
    pub lambda_min_ratio: Option<f64>,
    pub alpha: f64,
    pub eps_for_ridge: f64,
}

Options for generating a lambda path.

Fields

• nlambda - Number of lambda values (default: 100)
• lambda_min_ratio - Ratio for smallest lambda (default: 0.0001 if n < p, else 0.01)
• alpha - Elastic net mixing parameter (0 = ridge, 1 = lasso)
• eps_for_ridge - Small alpha to use for computing lambda_max when alpha=0 (default: 0.001)

Fields

nlambda: usize

Number of lambda values to generate

lambda_min_ratio: Option<f64>

Minimum lambda as a fraction of maximum

alpha: f64

Elastic net mixing parameter (0 = ridge, 1 = lasso)

eps_for_ridge: f64

Small alpha to use for ridge lambda_max computation
