Other criteria

Nelder and Wedderburn (1972) [282] Original GLM paper. For models selection, proposes comparing deviance to degrees of freedom. For well-fitting models, $L^{2}-df\approx 0$.

Goutis and Robert (1998) [168] Choice between nested models where the larger model $M_{2}$ is regarded as adequate. Computes the posterior distribution of the Kullback-Leibler distance between $p(y|\theta; M_{1})$ and $p(y|\theta; M_{2})$; the simpler model is accepted if (e.g.) the posterior mean is small enough. Fairly straightforward for GLMs, otherwise use MCMC.
