Referring to the pioneering work of the statistician George U. Yule (1903: 132134), Mittal (1991) calls this Yules Association Paradox (YAP).It is typical of spurious correlations between variables with a common cause, that is, variables that are dependent unconditionally (\(\alpha(D) \ne 0\)) but independent given the values of the common cause (\(\alpha(D_i) = 0\)). Causation can exist at the same time, but specifically occurs when one variable impacts the other.
