What is Guinnessometrics?
A refreshing alternative to random experiments.
To hear the main story, read Guinnessometrics: The Economic Foundation of Student’s t, Journal of Economic Perspectives (Fall 2008) and How Large Are Your G Values Gosset’s Guinnessometrics When a Little p Is Not Enough The American Statistician (2019) 73 sup1 (Special Issue on Statistical Inference in the 21st Century: A World Beyond p < 0.05)
[Media press release (April 24, 2019)]
To hear about the leading role that fermentation has played in scientific discovery – including oxygen, hello! – and how a brewer found through repeated experimentation that large scale randomized trials are nothing to boast about, read W.S. Gosset and Some Neglected Concepts of Experimental Statistics: Guinnessometrics II, Journal of Wine Economics (Winter 2011)
Leading experimental economists, such as Steve Levitt and John List, have not grasped the point. See Ziliak’s Balanced versus Randomized Field Experiments in Economics: Why W.S. Gosset aka ‘Student’ Matters, Review of Behavioral Economics 1 (1, Jan. 2014). (Final) Balanced vs Randomized Field Experiments Ziliak Rev Behavioral Economics 2014
Some of our top biometricians stand committed to the flawed approach made rote by Fisher. See, for example, my essay in The Lancet and reply to Stephen Senn: The Validus Medicus and a New Gold Standard (The Lancet, 2010); Significant Errors – Reply to Stephen Senn (The Lancet, 2010)
Guinnessometrics can improve the precision, efficiency, and ethics of any statistically-based study, including field experiments in economics, medicine, and drug trials. See, for example, The Unprincipled Randomization Principle in Economics and Medicine, by Stephen T. Ziliak and Edward R. Teather-Posadas, is forthcoming in the Oxford University Press Handbook on Professional Economic Ethics (New York: OUP, 2014), edited by George DeMartino and Deirdre N. McCloskey.
