💖 NAME 💖

Okay so this is Statistics::Descriptive::Smoother::Exponential(3pm) — yes, that whole gorgeous mouthful — hanging out in User Contributed Perl Documentation, with the little corner label Statis...ential(3pm) because the terminal is dramatic and truncates things. It implements exponential smoothing, and honestly? Iconic behavior. 💅

🎀 VERSION 🎀

version 3.0801 — that's the one, bestie. ✨

🦋 SYNOPSIS 🦋

         use Statistics::Descriptive::Smoother;
         my $smoother = Statistics::Descriptive::Smoother->instantiate({
                  method   => 'exponential',
                  coeff    => 0.5,
                  data     => [1, 2, 3, 4, 5],
                  samples  => [110, 120, 130, 140, 150],
           });
         my @smoothed_data = $smoother->get_smoothed_data();

🌸 DESCRIPTION 🌸

This module implements the exponential smoothing algorithm to smooth the trend of a series of statistical data. That's the whole assignment, and it ate. 💖

It works well for unsmoothed data with a big number of samples. If that's not your case, you might consider using the "Weighted Exponential" one. Lowkey important, bestie.

The algorithm implements this formula, periodt:

S(0) = X(0)

S(t) = C*S(t-1) + (1-C)*X(t)

where:

  • t = index in the series
  • S(t) = smoothed series value at position t
  • C = smoothing coefficient. Value in the [0;1] range. 0 means that the series is not smoothed at all, while 1 the series is universally equal to the initial unsmoothed value.
  • X(t) = unsmoothed series value at position t

💅 METHODS 💅

  • $stats->get_smoothed_data(); — Returns a copy of the smoothed data array. Slay. 🫶
