= Henry Rouanet
{c}
<Henry Rouanet> worked on <statistics> for researchers in psychology and the social sciences, emphasizing interpretable methods for analyzing actual data. His own account describes that aim and organizes his work by statistical problem rather than by an abstract sequence of prerequisites.https://helios2.mi.parisdescartes.fr/~lerb/rouanet/WelcomePage.html[Author's account of his scientific work]{ref}
With <Brigitte Le Roux>, he wrote <Geometric Data Analysis by Brigitte Le Roux and Henry Rouanet>. Its treatment of <correspondence analysis> and <principal component analysis> expresses multivariate data as weighted clouds in <Euclidean geometry>. The choice of weights and <metric> specifies which departures count as large; the resulting picture is part of the statistical model, not simply an illustration added afterward.<Geometric Data Analysis by Brigitte Le Roux and Henry Rouanet>[Chapters 2–4]{ref}
