Hi
I am using Matlab's GLM function:
[b,dev,stats] = glmfit(...)
Where can I get an output of the overall model fit (something like an omnibus test)?

Have you looked through the documentation for glmfit? It describes all the output in detail. In particular, the stats output is a structure that contains information about the fit (e.g. t-statistics and p-values for the fit coefficients).

Yes, but as I understand these are the statistics for the coefficients - not for the model overall, right?

That's true. I think if you use fitglm instead of glmfit (yeah, I know), it reports the model-level stats that you are looking for. Take a look at the methods for the model object (denoted mdl) that is the output from fitglm, as well as the first couple examples on that documentation page.
