Santa Runs Exponential Smoothing

Description

A screenshot of a tweet by John Rauser, @jrauser, shows a Follow button and a long statistical joke. The tweet reads: "My son's a little worried that Santa may skip our house because he was sometimes bad this year. I explained that Santa uses an exponentially weighted moving average to compute your goodness score, so more recent datapoints dominate and he's probably fine." The timestamp reads "5:15 PM - 23 Dec 2017," with visible engagement counts of "5,463 Retweets," "21,511 Likes," and footer icons showing 226 replies, 5.5K retweets, and 22K likes. The humor comes from applying a quantitative time-series smoothing method to a child's moral standing with Santa.
