Letter to editor: Common influencing factors are no evidence of association

A comment on an article by Callander, Newman, and Holt (2015) appeared in the Archives of Sexual Behavior pointing out a statistical fallacy: A common set of influencing factors can exist for two (or more) variables, while the random variables are uncorrelated or even independent. This is possible because after controlling for explanatory variables, the remaining partial correlation might be negative.
