7.13 ( ) In the evidence framework for RVM regression, we obtained the re-estimation formulae (7.87) and (7.88) by maximizing the marginal likelihood given by (7.85).

Extend this approach by inclusion of hyperpriors given by gamma distributions of the form (B.26) and obtain the corresponding re-estimation formulae for α and β by maximizing the corresponding posterior probability p(t,α, β|X) with respect to α

and β.
