Module yata::methods[−][src]

Expand description

Commonly used methods for manipulating timeseries. Every method implements Method trait.

To create a method instance use Method::new. To get new output value over the input value use Method::next.

// creating Weighted Moving Average of length `5`
use yata::prelude::*;
use yata::methods::WMA;

let mut wma = WMA::new(5, 20.0).unwrap();

let input_value = 34.51;
let output_value = wma.next(input_value);

Examples

use yata::prelude::*;
use yata::methods::SMA;

let mut sma = SMA::new(3, 5.0).unwrap();
sma.next(5.0);
sma.next(4.0);
assert_eq!(sma.next(6.0), 5.0);
assert_eq!(sma.next(2.0), 4.0);
assert_eq!(sma.next(-2.0), 2.0);
