absdiffcat-ergmTerm-5b2a4b77: Categorical absolute difference in nodal attribute

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

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	a vertex attribute specification (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.
