Geometrically weighted out-degree distribution
This term adds one network statistic to the model equal to the weighted out-degree distribution with decay parameter . This term can only be used with directed networks.
# binary: gwodegreeL(decay, fixed=FALSE, attrname=NULL, cutoff=30, levels=NULL, Ls=NULL)
decay: non-negative model parameter that is the same as theta_s in equation (14) in Hunter (2007).fixed: specify if the value supplied for decay may be fixed (if fixed=TRUE ), or it may be used as merely the starting value for the estimation in a curved exponential family model (the default).attrname: if specified, then separate degree statistics are calculated for nodes having each separate value of the attribute.cutoff: only relevant if fixed=FALSE . In that case it only uses this number of terms in computing the statistics to reduce the computational burden. Its default value can also be controlled by the gw.cutoff term option control parameter. (See control.ergm .)levels: a list of layer specifications. If given, degree of a node i is considered to be the number of edges in all layers, combined.Ls: either a Layer Logic specification formula (c.f. Layer Logic section in the Layer() documentation) or a list thereof (constructed by list() or c()).ergmTerm for index of model terms currently visible to the package.
