Two series that should have nothing to do with each other
Surprise me
GLOVIZ picked Solar generation DK from Energi Data Service (Energinet) and Humidity Johannesburg from Open-Meteo, paired them on time, and found a correlation of -0.846 over 17 matched observations. Two different institutions, two different measurement programmes, no shared mechanism. That is the point: with a thousand series, coincidences are cheap.
