---

function logpdf_normal_inverse_gamma_gaussian(x:Real, μ:Real, a2:Real, α:Real, β:Real) -> Real

Observe a Gaussian variate with a normal inverse-gamma prior.

• x: The variate.
• μ: Mean.
• a2: Variance.
• α: Shape of the inverse-gamma.
• β: Scale of the inverse-gamma.

Returns: the log probability density.
