The comparisons between the Cox proportional hazard model and the considered gamma and inverse Gaussian frailty models are based on the Akaike frozen cat food grocery storeWebwhich 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. frozen cauliflower air fryer timeWebGLM with a Gamma-distributed Dependent Variable. 1 Introduction ... ,family=gaussian(link="inverse")) then the estimated b’s from the Gamma and Normal models will probably be similar.
