Struct LinearModel 

Source 
pub struct LinearModel {
    pub coefficients: Vec<f64>,
    pub fit_intercept: bool,
    pub std_errors: Vec<f64>,

}
Expand description

A fitted OLS model with inferential output. When fit_intercept is true, coefficients[0] is the intercept and coefficients[1..] align with the predictor columns; the *_per_coef vectors are aligned the same way.

Implementations§

Source§

impl LinearModel

Source

pub fn predict_row(&self, x_row: &[f64]) -> f64

Source

pub fn predict(&self, x: &[f64], n: usize, p: usize) -> Vec<f64>
