gwidegree-ergmTerm-b37ed894: Geometrically weighted in-degree distribution

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

Geometrically weighted in-degree distribution

Description

This term adds one network statistic to the model equal to the weighted in-degree distribution with decay parameter decay parameter, which should be non-negative. This term can only be used with directed networks.

Usage

# binary: gwidegree(decay, fixed=FALSE, attr=NULL, cutoff=30, levels=NULL)

Arguments

decay	nonnegative decay parameter for the indegree frequencies; required if fixed=TRUE and ignored with a warning otherwise.
fixed	optional argument indicating whether the decay parameter is fixed at the given value, or is to be fit as a curved exponential-family model (see Hunter and Handcock, 2006). The default is FALSE , which means the scale parameter is not fixed and thus the model is a curved exponential family.
attr	a vertex attribute specification (see Specifying Vertex attributes and Levels (?nodal_attributes) for details.)
cutoff	This optional argument sets the number of underlying degree terms to use in computing the statistics when fixed=FALSE, in order to reduce the computational burden. Its default value can also be controlled by the gw.cutoff term option control parameter. (See ?control.ergm.)
levels	TODO (See Specifying Vertex attributes and Levels (?nodal_attributes) for details.)
