Une distribution gaussienne pour les notes des étudiants n’est pas un indicateur de rigueur.
Curving grades remains an unquestioned practice, in some contexts. Despite all the debunking which has been done since Terman's (in)famous work...

conditional distribution for individual components can be constructed
So the conditional distribution is conditioned on other components?
calculation once again involves inverting a NxN matrix as in the kernel space representation of regression
this is why we use MCMC or other distribution sampling technique instead
in equation B for the marginal of a gaussian, only the covariance of the block of the matrix involving the unmarginalized dimensions matters! Thus “if you ask only for the properties of the function (you are fitting to the data) at a finite number of points, then inference in the Gaussian process will give you the same answer if you ignore the infinitely many other points, as if you would have taken them all into account!”(Rasmunnsen)
