Cosmic Data Fusion
Cavendish Astrophysics, Cavendish Laboratory, Madingley Road,
We compare and combine cosmological parameter constraints from galaxy
peculiar velocities, the CMB and supernovae in the parameter space
$\Omega_m$, $h$ and $\sigma_8$.
We also outline a method for combining data sets using weightings, or
`Hyper-Parameters', and we compare the results of this approach with
those of a conventional approach by applying it to subsets of a CMB
