R: Evaluation on symmetrized (undirected) network

Symmetrize-ergmTerm {ergm} | R Documentation

## Evaluation on symmetrized (undirected) network

### Description

Evaluates the terms in `formula` on an undirected network constructed by symmetrizing the LHS network using one of four rules:

1. "weak" A tie (i,j) is present in the constructed network if the LHS network has either tie (i,j) or (j,i) (or both).

2. "strong" A tie (i,j) is present in the constructed network if the LHS network has both tie (i,j) and tie (j,i) .

3. "upper" A tie (i,j) is present in the constructed network if the LHS network has tie (\min(i,j),\max(i,j)) : the upper triangle of the LHS network.

4. "lower" A tie (i,j) is present in the constructed network if the LHS network has tie (\max(i,j),\min(i,j)) : the lower triangle of the LHS network.

### Usage

    # binary: Symmetrize(formula, rule="weak")

### Arguments

`formula` | a one-sided `ergm()`-style formula with the terms to be evaluated
`rule` | one of `"weak"`, `"strong"`, `"upper"`, `"lower"`
