WebNonparametric methods for undirected networks have focused on estimation of the graphon model. While the graphon model accounts for nodal heterogeneity, it does not account for network heterogeneity, a feature speci c to applications where multiple networks are observed. To address this setting of multiple networks, we propose a multi-graphon … WebJan 1, 2024 · Dynamic network models and graphon estimation. The Annals of Statistics, 47(4):2378-2403, 2024.

WebMotivated by these issues, we propose a novel local linear graphon estimator that uses covariates to account for node heterogeneity, and enables improved graphon estimation. We consider the setting where a single undirected network without self-loops is observed along with continuous covariates at each node. Webthe smoothness of the graphon is small, the minimax rate of graphon estimation is identical to that of nonparametric regression.
