"Webwhich do not look anything like a Gaussian or an inverse gamma, respectively. However, it can be shown that Jeﬀreys priors are limits of conjugate prior densities. For example, a Gaussian density N(µ 0,σ2) approaches a ﬂat prior as σ 0 → ∞, while the inverse gamma σ ∝ σ−(a+1)e−b/σ → 1/σ as a,b → 0. " - Gaussian inverse gamma
