My experience is that the values of latent variable from truncated normal
are easily to explode. You may want to add some truncations into your code.
Additionally, since you normalize the 1st diagnol element of covariance matrix
as 1, you can not still assume this matrix is wishart distributed. You can
check a recent paper (2000) in J. of Econometrics to see how to estimate
this kind of identified MNP model by Bayesian.
An easy way is to work on unidentified model, in which you specify priors
