Joint distribution of multivariate normal
NettetThe idea is to use the definition of conditional density f(y1 y2 = a) = fY1, Y2(y1, a) fY2(a). You know that the joint fY1, Y2 is a bivariate normal and that the marginal fY2 is a … Nettetthe asymptotic joint distribution for multivariate sample moments and apply it to both multivariate elliptical distributions and the multivariate skew-normal family.
