pub struct WSMA(/* private fields */);
Expand description
Wilder’s Smoothing Average of specified length
for timeseries of type ValueType
It is actually a simple EMA over length*2-1
periods
§Parameters
Has a single parameter length
: PeriodType
length
should be > 0
and < PeriodType::MAX
/2
§Input type
Input type is ValueType
§Output type
Output type is ValueType
§Examples
use yata::prelude::*;
use yata::methods::WSMA;
// WSMA of length=3
let mut wsma = WSMA::new(4, &2.0).unwrap();
wsma.next(&3.0);
wsma.next(&6.0);
assert_eq!(wsma.next(&9.0), 4.640625);
assert_eq!(wsma.next(&12.0), 6.48046875);
§Performance
O(1)
