absdiffcat-ergmTerm {ergm}R Documentation

Categorical absolute difference in nodal attribute

Description

This term adds one statistic for every possible nonzero distinct value of abs(attr[i]-attr[j]) in the network. The value of each such statistic is the number of edges in the network with the corresponding absolute difference.

Usage

# binary: absdiffcat(attr,
#                 base=NULL,
#                 levels=NULL)

# valued: absdiffcat(attr,
#                 base=NULL,
#                 levels=NULL,
#                 form="sum")

Arguments

attr

quantitative attribute (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.)

base

deprecated

levels

specifies which nonzero difference to include in or exclude from the model. (See Specifying Vertex attributes and Levels (?nodal_attributes) for details.)

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.

The argument base is retained for backwards compatibility and may be removed in a future version. When both base and levels are passed, levels overrides base.
