Right now I am in the middle of a graduate multivariate statistics but I am feeling to easy at the moment. As a mathematician I study univariate statistics from "The theory of statistical inference : Shelemyahu Zacks" wich is a completely theoretical with measure formalism and I want to know if it exists an analogue for multivariate.
I have been recommended to look for statistics from differential geometry perspective ... But also I don´t found anything interesting.
Could someone help me with references on books, papers ... ?
