function update_lazy_linear_matrix_normal_inverse_wishart_multivariate_gaussian(x:Expression<Real[_]>, a:Expression<Real[_]>, N:Expression<Real[_,_]>, Λ:Expression<LLT>, c:Expression<Real[_]>, V:Expression<LLT>, k:Expression<Real>) -> (Expression<Real[_,_]>, Expression<LLT>, Expression<LLT>, Expression<Real>)

Update the parameters of a Gaussian variate with linear transformation of matrix-normal-inverse-Wishart prior.

• x: The variate.
• a: Scale.
• N: Prior precision times mean matrix.
• Λ: Prior precision.
• c: Offset.
• V: Prior variance shape.
• k: Prior degrees of freedom.

Returns: the posterior hyperparameters N', Λ', V' and k'.
