Abstract: An assumption-lean inference framework is discussed for regression models built for network-linked data. Two specific network models are explored: the graphon model and the generalized random dot product model, each with different choices of appropriate node-level network statistics. A phase transition phenomenon is discovered in both models. In denser regimes, consistent bootstrap schemes are provided for two important classes of network statistics. In sparser scenarios, a down-sampling inference method is offered that is consistent under mild conditions, albeit with a slightly slower convergence rate.
