Description

Jira ticket to track the implementation of the Univariate statistics required for the updated SummaryStatistics API.
The implementation would be "storeless". It should be used for calculating statistics that can be computed in one pass through the data without storing the sample values.

Currently I have the definition of API as (this might evolve as I continue working)

public interface DoubleStorelessUnivariateStatistic extends DoubleSupplier {

    DoubleStorelessUnivariateStatistic add(double v);

    long getCount();

    void combine(DoubleStorelessUnivariateStatistic other);
}
