Least Committed basic belief density induced by a multivariate Gaussian pdf

We consider here the case where our knowledge is partial and based on a betting density function which is n-dimensional Gaussian. The explicit formulation of the least committed basic belief density (bbd) of the multivariate Gaussian pdf is provided. Beliefs are then assigned to hyperspheres and the bbd follows a chi
