Confounding

(重定向自Confounding variables)
Illustration of a simple confounding case: in this graphical model, given Z, there is no association between X and Y.  However, not observing Z will create spurious association between X and Y. In the latter case, Z is called a confounding factor.

In statistics, a confounding variable (also confounding factor, a confound, or confounder) is an extraneous variable in a statistical model that correlates (directly or inversely) with both the dependent variable and the independent variable.

A spurious relationship is a perceived relationship between an independent variable and a dependent variable that has been estimated incorrectly because the estimate fails to account for a confounding factor. The incorrect estimation suffers from omitted-variable bias.
