Susan Holmes, "Multivariate data anaysis: the French way"
http://projecteuclid.org/euclid.imsc/1207580085

Abstract: This paper presents exploratory techniques for multivariate data, many of them well known to French statisticians and ecologists, but few well understood in North American culture. We present the general framework of duality diagrams which encompasses discriminant analysis, correspondence analysis and principal components, and we show how this framework can be generalized to the regression of graphs on covariates.

Интригующий отрывочег:

Some French statisticians, fed Bourbakist mathematics and category theory in the 60’s and 70’s as all mathematicians were in France at the time, suffered from abstraction envy. Having completely rejected the probabilistic enterprise as usеless for practical reasons, they composed their own abstract framework for talking about data in a geometrical context.
