function observe_multivariate_normal_inverse_gamma(x:Real[_], μ:Real[_], Λ:Real[_,_], α:Real, β:Real) -> Real

Observe a multivariate normal inverse-gamma variate.

  • x: The variate.
  • μ: Mean.
  • Λ: Precision.
  • α: Shape of inverse-gamma on scale.
  • β: Scale of inverse-gamma on scale.

Returns: the log probability density.
