%description
Cross-validated eigenvalues are estimated by splitting a graph into two
parts, the training and the test graph. The training graph is used to
estimate eigenvectors, and the test graph is used to evaluate the
correlation between the training eigenvectors and the eigenvectors of the
test graph. The correlations follow a simple central limit theorem that
can be used to estimate graph dimension via hypothesis testing, see Chen
et al. (2021) <arXiv:2108.03336> for details.
