WM Briggs, the Statistician to the Stars!

The Epidemiologist Fallacy marries the Ecological Fallacy with the P-value Fallacy. The Ecological Fallacy is when it is said X causes Y, but X is not measured, and instead a proxy is. The P-value fallacy is to suppose a wee p-value has confirmed X causes Y. The P-value Fallacy can also be done with Bayesian methods, as in the example given.

The paper shown does not use P-values, but does use parameter-based Bayesian measures which exaggerate evidence. See the above link for an explanation.

See https://wmbriggs.com for a complete description. I am a wholly independent vagabond writer, statistician, scientist and consultant. Previously a Professor at the Cornell Medical School, a Statistician at DoubleClick in its infancy, a Meteorologist with the National Weather Service, and a sort of Cryptologist with the US Air Force (the only title I ever cared for was Staff Sergeant Briggs).

My PhD is in Mathematical Statistics, though I am now a Data Philosopher (I made that up), Epistemologist, Probability Puzzler, Unmasker of Over-Certainty, and (self-awarded) Bioethicist. My MS is in Atmospheric Physics, and Bachelors is in Meteorology & Math.

Author of Uncertainty: The Soul of Modeling, Probability & Statistics, a book which calls for a complete and fundamental change in the philosophy and practice of probability & statistics; author of two other books and dozens of works in fields of statistics, medicine, philosophy, meteorology and climatology, solar physics, and energy use appearing in both professional and popular outlets.
