Hierarchical Community Detection by Recursive Partitioning
Tianxi Li, Lihua Lei, Sharmodeep Bhattacharyya, Purnamrita Sarkar, Peter Bickel, and Elizaveta Levina
Hierarchical community detection on networks by a recursive spectral partitioning strategy, which is shown to be effective and efficient in Li, Lei, Bhattacharyya, Sarkar, Bickel, and Levina (2018) <arXiv:1810.01509>. The package also includes a data generating function for a binary tree stochastic block model, a special case of stochastic block model that admits hierarchy between communities.

This code provides a method to fit the hidden compact representation model as well as to identify the causal direction on discrete data.
We implement an effective solution to recover the above hidden compact representation under the likelihood framework.
