Stop Doing Time Series

STOP DOING TIME SERIES •DATA WERE NEVER SUPPOSED TO BE PLOTTED AGAINST TIME •YEARS OF ACF PLOTS yet NO BETTER METHOD FOUND THAN LOOKING AT THE DATA WITH YOUR EYES •Wanted to predict something anyway for a laugh? We had a tool for that: it was called LINEAR REGRESSION "My data are not iid, it has autocorrelation" - Statements dreamed up by the utterly Deranged LOOK AT WHAT THEY WANT US TO BELIEVE stationary (phi=0.8) BIC = k ln(n) − 2ln(L̂) They say this is stationary, BUT ITS CLEARLY MOVING Back in my day BIC made LIGHTERS and PENS "Wiener process", "Dickey- Fuller test", THEY KNOW YOU'LL BELIEVE ANYTHING "Hello I would like apples please" THEY HAVE PLAYED US FOR ABSOLUTE FOOLS

This is a satirical statistics meme arguing that time-series analysis is needlessly complicated and that plots visibly show movement despite claims of stationarity. It mocks statistical jargon such as ACF, BIC, linear regression, Wiener process, and the Dickey-Fuller test, presenting ordinary apples as an absurdly simple alternative. The joke is used as a reaction to overly technical explanations or suspicious statistical claims.
