Joint Estimation of Sparse Multilayer Networks via Graph Limits
A nonparametric joint estimator based on blockmodel approximations is developed, which captures each layer's varying sparsity and connection structure, accounting for heterogeneity via shared latent variables across all layers, and enables high-resolution estimation even in sparser layers.
