If you do you'll see MultinormalDistribution colored red indicating a conflict. 2) this works: Web2) The covariance matrices of the two bivariate normals need to be positive definite. The first constraint can be guaranteed by specifying the weights as follows: w1 = Exp [w]/ (1 + Exp [w]); where w is unconstrained. The second constraint can be enforced by using the Cholesky Decomposition of the covariance matrices as below.
