solved - thx

I am in need to know the volume of a n-dimensional ellipsoid, but the matrix from which the principal axis are calculated is a singular system. This might sound strange, nevertheless, the explanation in the linked pdf will show you what I am talking about. I guess that the solution is pretty...

yes, I do know the signs and would like to know how the positive vector components are distributed conditional on the information that the others are below zero (but I do not know what value they hold - only the signs). so what I want is to condition the multivariate normal distribution on an...

Hi all First of all, I am new here but I am not new to statistics. But I need your help:smile: I do have a multivariate normal distribution: x~p(mu,sig) the vector x has to groups of variables, those that I know are below zero (x_bz), and those that I know are above zero (x_az). I am...
