Homepage: https://metacpan.org/release/Statistics-Welford
Description-en: Standard statistics using Welford's algorithm
Statistics::Welford provides standard statistics (mean value,
variance, standard deviation, minimum and maximum value as well as
the number of elements) using Welford's algorithm.
.
Welford's algorithm is much more resource efficient compared to the
naïve algorithm implemented in e.g. Statistics::Basic::StdDev or
Catmandu::Fix::stat_stddev. It especially does not need to load all
values into RAM at the same time, i.e. does not require an array
containing all values.
.
