absdiff-ergmTerm-9fc8de5a: Absolute difference in nodal attribute

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

Absolute difference in nodal attribute

Description

This term adds one network statistic to the model equaling the sum of abs(attr[i]-attr[j])^pow for all edges ⁠(i,j)⁠ in the network.

Usage

# binary: absdiff(attr,
#                 pow=1)

# valued: absdiff(attr,
#                 pow=1,
#                 form="sum")

Arguments

attr	a vertex attribute specification (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.)
pow	power to which to take the absolute difference
form	character how to aggregate tie values in a valued ERGM

Note

ergm versions 3.9.4 and earlier used different arguments for this term. See ergm-options for how to invoke the old behaviour.
