nodeicov-ergmTerm-02d64b5b: Main effect of a covariate for in-edges

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

Main effect of a covariate for in-edges

Description

This term adds a single network statistic for each quantitative attribute or matrix column to the model equaling the total value of attr(j) for all edges (i,j) in the network. This term may only be used with directed networks. For categorical attributes, see nodeifactor .

Usage

# binary: nodeicov(attr)

# valued: nodeicov(attr, form="sum")

Arguments

attr	a vertex attribute specification (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.
