Expand description

Result of a ridge regression fit.

Contains the fitted model coefficients, predictions, and diagnostic metrics.

§Fields

lambda - The regularization strength used
intercept - Intercept coefficient (never penalized)
coefficients - Slope coefficients (penalized)
fitted_values - Predicted values on training data
residuals - Residuals (y - fitted_values)
df - Approximate effective degrees of freedom
r_squared - Coefficient of determination
adj_r_squared - Adjusted R²
mse - Mean squared error
rmse - Root mean squared error
mae - Mean absolute error
log_likelihood - Log-likelihood of the model (for model comparison)
aic - Akaike Information Criterion (lower = better)
bic - Bayesian Information Criterion (lower = better)

§Example

let fit = ridge_fit(&x, &y, &options).unwrap();

// Access model coefficients
println!("Intercept: {}", fit.intercept);
println!("Slopes: {:?}", fit.coefficients);

// Access predictions and diagnostics
println!("R²: {}", fit.r_squared);
println!("RMSE: {}", fit.rmse);
println!("AIC: {}", fit.aic);
