Struct TTest 

pub struct TTest { /* private fields */ }

Welch’s t-test on two streaming sample populations.

Uses Welford’s incremental algorithm for the running mean and variance, so it does not need to store individual samples.

Implementations

impl TTest

pub fn new() -> Self

Create an empty t-test.

pub fn push(&mut self, value: f64, class: u8)

Add a new measurement. class must be 0 or 1.

pub fn t_value(&self) -> f64

Compute Welch’s t-statistic. Returns 0.0 if not enough samples.

Trait Implementations

impl Default for TTest

fn default() -> TTest

Returns the “default value” for a type.
