%description
Implements Inductive Node-Splitting Cross-Validation (INCV) for selecting
the number of communities in stochastic block models. Provides f-fold and
random-split node-level cross-validation, along with competing methods
including CROISSANT, Edge Cross-Validation (ECV), and Node
Cross-Validation (NCV). Supports both SBM and Degree-Corrected Block
Models (DCBM), with multiple loss functions (L2, binomial deviance, AUC).
Includes network simulation utilities for SBM, RDPG, and latent space
models.
