Statisticians have pioneered two approaches to causal inference that have proven influential in the natural and behavioral sciences. The oldest dates back to Yule (1896), who wrote extensively about ‘illusory’ correlations, by which he meant correlations that should not be endowed with a causal interpretation. To distinguish between the illusory and non-illusory correlations, Yule invented partial correlation to ‘control’ ...
