Fallibility in estimating direct effects
Fallibility in estimating direct effects is a scholarly work by Stephen R Cole and Miguel Hernán, published in 2002 in ''International Journal of Epidemiology''. The main subjects of the publication include health economics, medicine, causality, missing data, outcome, indirect effect, causal inference, econometrics, confounding, causal model, and statistics. The authors use causal graphs and a partly hypothetical example from the Physicians' Health Study to explain why a common standard method for quantifying direct effects (i.e. stratifying on the intermediate variable) may be flawed.
