Function tech_analysis::rational_quadratic

pub fn rational_quadratic(
    src: &Series,
    look_back: i32,
    relative_weight: f32,
    start_at_bar: i32
) -> Result<Series, Box<dyn Error>>

Calculates the rational quadratic value for a given set of parameters.

This function takes a series of values, a lookback period, a relative weight, and a starting point. It then calculates the rational quadratic value for each element in the series based on the provided parameters.

Arguments

• src - The input series of values.
• look back - The look back period used in the calculation.
• relative_weight - The relative weight used in the calculation.
• start_at_bar - The starting point for the calculation.

Returns

A new series containing the calculated rational quadratic values.

Example

use polars::prelude::*;
use tech_analysis::rational_quadratic;
let src = Series::new("data",vec![1.0, 2.0, 3.0, 4.0, 5.0]);
let result = rational_quadratic(&src, 2, 3.0, 1);
eprintln!("{:?}", result);
println!("{:?}", result);
