William Sealy Gosset, 1876-1937

William Sealy Gosset (13 juin 1876 – 16 octobre 1937) connu sous le pseudonyme Student est un statisticien anglais. Employé de la brasserie Guinness pour stabiliser le goût de la bière, il a ainsi inventé le test de Student. Le test de Student est aujourd'hui utilisé de manière standard en économétrie pour tester la nullité d'un coefficient dans une régression linéaire normale.


d(A, B) = \min_{i \in A, j \in B}(d_{ij}) d(A, B) = \sup_{i \in A, j \in B}(d_{ij}) d(A, B) = \frac{1}{card(A)card(B)}\sum_{i \in A, j \in B}{d_{ij}}

d(A, B) = d(g_A, g_B)~ d(A, B) = \frac{w_A w_B}{w_A + w_B} d(g_A, g_B) \log(ratio) \neq 0
