observe_inverse_gamma_gaussian

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

Observe a Gaussian variate with an inverse-gamma distribution over the variance.

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

Returns: the log probability density.
