linreg is a small crate that calculates linear regressions. It works without
stdlib or memory allocation and has few dependencies. Example:
let xs: Vec<f64> = vec![1.0, 2.0, 3.0, 4.0, 5.0];
let ys: Vec<f64> = vec![2.0, 4.0, 5.0, 4.0, 5.0];
assert_eq!(Some((0.6, 2.2)), linear_regression(&xs, &ys));It supports tuples, separate vectors for x and y values and template floating point types.
