We characterize the existence of the maximum likelihood estimator for discrete exponential families. Our criterion is simple to apply, as we show in various settings, most notably for exponential models of random graphs. As application we point out the size of independent identically distributed samples for which the maximum likelihood estimator exists with high probability.

Graph model selection using maximum likelihood
TLDR
This work designs and implements MCMC algorithms for computing the maximum likelihood for four popular models: a power-law random graph model, a preferential attachment models, a small-world model, and a uniform random graph models, using Maximum Likelihood to compare graph models and select their parameters.

TLDR
The core statistical notions of "sample" and "population" in the ERGM framework are clarified, and the process that generates the population graph from the observation process is separated, and likelihood-based inference in finite-, super-, and infinite-population scenarios are reviewed. Expand
