Description:

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. .
