Two series that should have nothing to do with each other
Surprise me
GLOVIZ picked PM2.5 Paris from OpenAQ and Consumer price index FIN from International Monetary Fund, paired them on time, and found a correlation of 0.205 over 14 matched observations. Two different institutions, two different measurement programmes, no shared mechanism. That is the point: with a thousand series, coincidences are cheap.
