Symmetrize-ergmTerm-61cab8ac: Evaluation on symmetrized (undirected) network

In ergm: Fit, Simulate and Diagnose Exponential-Family Models for Networks

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"
