Georges Darmois was a French
mathematician
and statistician. He pioneered in the theory of sufficiency
, in stellar statistics, and in factor analysis
. He was also one of the first French mathematicians to teach British mathematical statistics.
He is one of the eponyms of the Koopman–Pitman–Darmois theorem and sufficient statistics and exponential families
.
Darmois earned his doctorate
from the University of Paris
in 1921, under supervision of Édouard Goursat
. In 1949, he succeeded Maurice René Fréchet
on the Chair of Calculus of Probabilities and Mathematical Physics at the University of Paris.

Sufficiency (statistics)
In statistics, a sufficient statistic is a statistic which has the property of sufficiency with respect to a statistical model and its associated unknown parameter, meaning that "no other statistic which can be calculated from the same sample provides any additional information as to the value of...

Factor analysis
Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved, uncorrelated variables called factors. In other words, it is possible, for example, that variations in three or four observed variables...

Exponential family
In probability and statistics, an exponential family is an important class of probability distributions sharing a certain form, specified below. This special form is chosen for mathematical convenience, on account of some useful algebraic properties, as well as for generality, as exponential...

Edouard Goursat
Édouard Jean-Baptiste Goursat was a French mathematician, now remembered principally as an expositor for his Cours d'analyse mathématique, which appeared in the first decade of the twentieth century. It set a standard for the high-level teaching of mathematical analysis, especially complex analysis...
