Struct nanostat::Summary

pub struct Summary {
    pub n: f64,
    pub mean: f64,
    pub variance: f64,
}

A statistical summary of a normally distributed data set.

Created from an iterable of f64s:

let summary: nanostat::Summary = vec![0.1, 0.45, 0.42].iter().collect();

Fields

n: f64

The number of measurements in the set.

mean: f64

The arithmetic mean of the measurements.

variance: f64

The sample variance of the data set.

Implementations

impl Summary

pub fn std_dev(&self) -> f64

The standard deviation of the sample.

pub fn std_err(&self) -> f64

The standard error of the sample.

pub fn compare(&self, other: &Summary, confidence: f64) -> Difference

Calculate the statistical difference between the two summaries using a two-tailed Welch’s t-test. The confidence level must be in the range (0, 100).
