The product term, given by 'captial' pi, (\(Π\)), acts very much like the summation sign, but instead of adding we multiply over the elements ranging from j=1 to j=p.Inside this product is the familiar univariate normal distribution where the random variables are subscripted by j.In this case, the elements of the random vector, \(\mathbf { X } _ { 1 } , …
