Function smartnoise_runtime::components::raw_moment::raw_moment

pub fn raw_moment(data: &ArrayD<Float>, order: u32) -> Result<ArrayD<Float>>

Accepts data and returns sample estimate of kth raw moment for each column.

Arguments

• data - Data for which you would like the kth raw moments.
• order - Number representing the kth moment you want.

Return

kth sample moment for each column.

Example

use ndarray::{ArrayD, arr2, arr1};
use smartnoise_runtime::components::raw_moment::raw_moment;
use smartnoise_validator::Float;
let data: ArrayD<Float> = arr2(&[ [1., 1., 1.], [2., 4., 6.] ]).into_dyn();
let second_moments = raw_moment(&data, 2).unwrap();
assert_eq!(second_moments, arr2(&[[2.5, 8.5, 18.5]]).into_dyn());
