Function smartnoise_runtime::utilities::noise::sample_gaussian_truncated

pub fn sample_gaussian_truncated(
    min: f64, 
    max: f64, 
    shift: f64, 
    scale: f64, 
    enforce_constant_time: bool
) -> Result<f64>

Sample from truncated Gaussian distribution.

This function uses a rejection sampling approach. This means that values outside of the truncation bounds are ignored, rather than pushed to the bounds (as they would be for a censored distribution).

Arguments

• shift - The expectation of the untruncated Gaussian distribution.
• scale - The scaling parameter (standard deviation) of the untruncated Gaussian distribution.
• min - The minimum value you want to allow to be sampled.
• max - The maximum value you want to allow to be sampled.

Return

A draw from a Gaussian(shift, scale) truncated to [min, max].

Example

use smartnoise_runtime::utilities::noise::sample_gaussian_truncated;
let n= sample_gaussian_truncated(0.0, 1.0, 0.0, 2.0, false);
