[−][src]Struct average::Mean
Estimate the arithmetic mean of a sequence of numbers ("population").
Example
use average::Mean; let a: Mean = (1..6).map(f64::from).collect(); println!("The mean is {}.", a.mean());
Methods
impl Mean
[src]
pub fn new() -> Mean
[src]
Create a new mean estimator.
pub fn is_empty(&self) -> bool
[src]
Determine whether the sample is empty.
pub fn mean(&self) -> f64
[src]
Estimate the mean of the population.
Returns 0 for an empty sample.
pub fn len(&self) -> u64
[src]
Return the sample size.
