phi.stat

<code>[n x n]</code> adjacency matrix or general relational weight matrix of which \(A_ij\) indicates relationship from \(i\) to \(j\).

a vector of \(n\) nominal or binary, one-dimensional observations.

A test statistic of \(\Phi\) is to test network dependence in categorical observations.

When network dependence is present, that is when social relations can engender dependence in the outcome of interest, treating such observations as independent results in invalid, anti-conservative statistical inference. We propose a test of independence among observations sampled from a single network <arXiv:1710.03296>.
