Struct linregress::RegressionParameters

pub struct RegressionParameters {
    pub intercept_value: f64,
    pub regressor_names: Vec<String>,
    pub regressor_values: Vec<f64>,
}

A parameter of a fitted RegressionModel given for the intercept and each regressor.

The values and names of the regressors are given in the same order.

You can obtain name value pairs using pairs.

Fields

intercept_value: f64

regressor_names: Vec<String>

regressor_values: Vec<f64>

Methods

impl RegressionParameters

pub fn pairs(self) -> Vec<(String, f64)>

Returns the parameters as a Vec of tuples of the form (name: String, value: f64).

Usage

use linregress::{FormulaRegressionBuilder, RegressionDataBuilder};

let y = vec![1.,2. ,3. , 4.];
let x1 = vec![4., 3., 2., 1.];
let x2 = vec![1., 2., 3., 4.];
let data = vec![("Y", y), ("X1", x1), ("X2", x2)];
let data = RegressionDataBuilder::new().build_from(data)?;
let model = FormulaRegressionBuilder::new().data(&data).formula("Y ~ X1 + X2").fit()?;
let pairs = model.parameters.pairs();
assert_eq!(pairs[0], ("X1".to_string(), -0.0370370370370372));
assert_eq!(pairs[1], ("X2".to_string(), 0.9629629629629629));
