head.mmsbm: Identify nodes with most frequent membership in latent groups

In NetMix: Dynamic Mixed-Membership Network Regression Model

Identify nodes with most frequent membership in latent groups

Description

The function lists the nodes (optionally, node-time periods) that most frequently instantiate membership in each latent group.

Usage

## S3 method for class 'mmsbm'
head(x, n = 6, t = NULL, node = TRUE, t.correct = FALSE, ...)

Arguments

x	An object of class mmsbm, a result of a call to mmsbm.
n	Numeric or integer; specifies how many units will be identified for each group.
t	Optional vector of time periods to be used for assessing latent group membership.
node	Logical; indicates whether latent group memberships should be averaged at the node level. If FALSE, the function returns the node-time period units with highest estimated membership in each latent group.
t.correct	Logical; indicates whether latent group memberships should be corrected for temporal trends. If TRUE, the function returns the node-time period units with highest estimated membership in each latent group.
...	Currently ignored

Value

List of length n.blocks. Each entry contains a sorted vector of average latent membership probabilities of length n.

## Estimate model with 2 groups
