pub struct WeightedMean { /* fields omitted */ }
Estimate the weighted and unweighted arithmetic mean of a sequence of
numbers ("population").
use average::WeightedMean;
let a: WeightedMean = (1..6).zip(1..6)
.map(|(x, w)| (f64::from(x), f64::from(w))).collect();
println!("The weighted mean is {}.", a.mean());
Create a new weighted and unweighted mean estimator.
Add an observation sampled from the population.
Determine whether the sample is empty.
Might be a false positive if the sum of weights is zero.
Return the sum of the weights.
Returns 0 for an empty sample.
Estimate the weighted mean of the population.
Returns 0 for an empty sample.
Merge another sample into this one.
