Dataset
Directors
Firm-director matched records with synthetic regressors and outcome.
Graph Summary
A difficult real graph with slow convergence in the old benchmarks.
The primary benchmark graph is built from unique (id1, id2) pairs. The figure shows a binned sparsity pattern of the bipartite incidence block, with both partitions relabeled to contiguous integer identifiers. This block is the off-diagonal part of the corresponding graph Laplacian.
Variables
Columns in the clean CSV:
The v1 graph uses id1 and id2. No additional identifier-like columns are included in this clean v1 CSV.
Source Notes
Firm-director matched records based on SUNAT data collected by the author.
Identifiers are anonymized; regressors and outcome are synthetic benchmark variables.
