In aaamini/nett: Network Analysis and Community Detection

Estimate community number with SNAC+

Description

Applying SNAC+ test sequentially to estimate community number of a network fit to DCSBM

Usage

snac_select(
  A,
  Kmin = 1,
  Kmax,
  alpha = 1e-05,
  labels = NULL,
  cluster_fct = spec_clust,
  ...
)

Arguments

A	adjacency matrix.
Kmin	minimum candidate community number.
Kmax	maximum candidate community number.
alpha	significance level for rejecting the null hypothesis.
labels	a matrix with each column being a row label vector for a candidate community number. If not provided, will be computed by cluster_fct.
cluster_fct	community detection function to get label vectors to compute SNAC+ statistics (in snac_test), by default using spec_clust.
...	additional arguments for cluster_fct.

Value

estimated community number.
