Abstract
The limited observational performances which can be achieved on large collections of faint objects do not allow to derive intrisic stellar parameters such as distance, mass, age, space velocity, chemical composition of individual stars. However some information relevant to the distribution of these quantities is reflected in the n-dimensional distribution of observables : connecting observed distributions to the physical processes they come from is basically a multivariate problem for which some of us developped a synthetic approach of galaxy modelling (Robin, Crézé 1986, Bienaymé et al. 1987).
