Crate average [−] [src]

This crate provides estimators for the weighted and unweighted average of a sequence of numbers, and for their standard errors. The typical workflow looks like this:

1. Initialize your estimator of choice (Average, AverageWithError, WeightedAverage or WeightedAverageWithError) with new().
2. Add some subset (called "samples") of the sequence of numbers (called "population") for which you want to estimate the average, using add() or collect().
3. Calculate the arithmetic mean with mean() and its standard error with error().

You can run several estimators in parallel and merge them into one with merge().

Example

use average::AverageWithError;

let mut a: AverageWithError = (1..6).map(Into::into).collect();
a.add(42.);
println!("The average is {} ± {}.", a.mean(), a.error());
