The best thing about being a statistician is that you get to play in everyone's backyard.

-- John Tukey

Laplace, Pierre-Simon
French
1749-1827
...👇

Co-invented Bayesian statistics. Invented exponential families (Laplace transform), conjugate prior distributions, asymptotic analysis of estimators (including negligibility of regular priors). Used maximum-likelihood and posterior-mode estimation and considered (robust) loss functions

#question

You are given two indistinguishable envelopes, each containing money, one contains twice as much as the other. You may pick one envelope and keep the money it contains. Having chosen an envelope at will, but before inspecting it, you are given the chance to switch envelopes. Should you switch?

Statisticians, like artists, have the bad habit of falling in love with their models.

Peirce, Charles Sanders
American
1839-1914
...

Formulated modern statistics in "Illustrations of the Logic of Science" (1877–1878) and "A Theory of Probable Inference" (1883). With a repeated measures design, introduced blinded, controlled randomized experiments (before Fisher). Invented optimal design for experiments on gravity, in which he "corrected the means". He used correlation, smoothing, and improved the treatment of outliers. Introduced terms "confidence" and "likelihood" (before Neyman and Fisher). While largely a frequentist, Peirce's possible world semantics introduced the "propensity" theory of probability. See the historical books of Stephen Stigler
