5.8 Gamma-Poisson conjugate family 5/8

5.8.1 Potential priors?

$\tau$ is postif and continuous

We have 3 probability models :

• Gamma : $f(\tau) \propto \tau^{s-1} e^{-r\tau}$

• Weibull : $f(\tau) \propto \tau^{s-1} e^{(-r\tau)^s}$

• F : $f(\tau) \propto \tau^{s/2 - 1} (1 + \tau) ^ -s$

Quiz! Which one ?
