Struct RunningMoments 

pub struct RunningMoments { /* private fields */ }

Count, mean and spread of a stream of values, updated one value at a time with Welford’s method.

Implementations

impl RunningMoments

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

Adds value. A value that is not finite is left out.

pub fn count(&self) -> u64

Number of finite values pushed.

pub fn mean(&self) -> Option<f64>

Returns the mean, or None before any value.

pub fn standard_deviation(&self) -> Option<f64>

Returns the sample standard deviation, with n - 1 in the denominator, or None below two values.

pub fn summary(&self) -> ReplicateSummary

Returns the count, mean, standard deviation and 95% confidence interval of the values so far.
